Flying to Lima on Points: AAdvantage, United, LifeMiles and Aeroplan Compared for the Same Route

Most “best programs for South America” articles compare Aeroplan to LifeMiles at 30,000 feet and leave you no closer to booking anything. This one does the opposite. I picked one city — Lima — and priced the same routing across the four programs that actually reach it well, because the honest answer is not “one program wins,” it’s “the right program depends on which gateway you’re flying from and which cabin you want.” Peru is one of the few genuinely deep award markets in South America, with nonstop options on American from Miami and Dallas, United from Houston and Newark, Delta from Atlanta, plus Avianca via Bogotá and Copa via Panama for anyone flexible on connections.

Below is the full picture: what each program prices this route at, how the routings actually stitch together, the domestic Lima-to-Cusco leg every reader eventually needs, and the specific traps I’d tell a friend to avoid before they hit “transfer” on any of these currencies.

Why Lima is a real award market, not a token South America mention

Buenos Aires and Santiago get most of the airtime in points articles, but Lima is where the depth actually is. Lima is served nonstop from Miami, Houston, Atlanta, Newark, JFK, Los Angeles, Dallas and Fort Lauderdale — eight US gateways, plus Salt Lake City on Delta’s newer seasonal service — which is more than any other South American capital gets from North American carriers. That density is what makes the program comparison meaningful. On most award routes, one alliance dominates and there is no real choice; on Lima, oneworld, Star Alliance and SkyTeam all have skin in the game.

Two facts about the destination itself shape the strategy. First, U.S. citizens do not need a visa for tourism, and the process at Jorge Chávez is straightforward with a passport valid six months past arrival. Second, almost nobody actually flies to Lima and stays in Lima — the real destination is Cusco, the Sacred Valley and Machu Picchu, which means every award you book needs to account for the domestic Lima–Cusco leg. I’ll cover that below, and it is not the piece to burn miles on.

American AAdvantage: the cleanest way to book Lima if you can fly from Miami or Dallas

American’s structural advantage here is that Peru sits in “South America – Short Haul,” a zone that also includes Colombia, Ecuador and Guyana, which means it prices at the cheaper of the two South America bands on the AAdvantage partner chart. AA also runs meaningful nonstop capacity of its own: multiple daily flights on the Miami–Lima route and a daily nonstop from Dallas–Fort Worth.

The number worth memorizing is 27,500 AAdvantage miles each way in business class, with economy seats appearing for as few as 13,500 miles one-way when American runs a targeted sale on the route. That is not the standard price — AAdvantage now uses dynamic pricing on AA-operated flights and the standard business rate is higher — but the deal has surfaced repeatedly over the past 18 months, sometimes with a stack of seats available on the same flight. Sign up for award alerts, and when it hits, transfer and book immediately.

When there is no sale, American’s own metal typically prices in the 30,000-mile range one-way in economy and 45,000 to 60,000 in business class, depending on demand. That is still a strong redemption on a flight where cash fares in business regularly clear $1,500 to $2,000 round trip. Availability tends to be better midweek and outside of the June–August peak.

A subtle but useful point: Alaska Atmos Rewards is also a way into this same American metal, with partner business class awards to Lima priced around 35,000 points one-way. Alaska and Hawaiian merged their programs into Atmos Rewards in 2025, so if you have leftover HawaiianMiles or Mileage Plan balances, they now sit in one account and can hit the same AA cabins. That gives you two ways at oneworld space instead of one.

Where AAdvantage falls apart is if you cannot easily reach Miami or Dallas. Positioning legs eat into the value fast, and American does not open its own domestic segments generously on award routings.

United MileagePlus: the closest thing to a “sure thing” from Houston or Newark

United flies its own nonstop to Lima daily from both Houston (IAH) and Newark (EWR), and MileagePlus is one of the easier programs to earn thanks to 1:1 transfers from Chase and Bilt. The catch, and it is a real one, is that United MileagePlus has switched to a dynamic pricing model, meaning award prices are tied to cash prices on both United-operated and partner-operated flights. There is no chart anymore for United metal.

What that looks like in practice on the Houston–Lima nonstop: economy saver awards typically clear at 30,000 to 35,000 miles one-way when they open, with Polaris business class starting near 60,000 miles when the airline opens saver space and climbing well into six figures when it does not. United now discounts award tickets by at least 10% for primary cardholders and at least 15% for Premier members with a United card, which does meaningfully change the math if you carry the Explorer or higher tier — an award that lists at 30,000 becomes 27,000 for a general cardholder.

There are two ways to use United miles smartly on this route. First, watch the calendar view on united.com and pounce on saver-priced economy seats when they appear — they do, especially on the Newark redeye. Second, use the Excursionist Perk, which is genuinely useful here: you can book a round-trip that includes a free segment within South America, so a routing like Newark to Lima, Lima to Cusco or Buenos Aires as a free excursion, and back home from a different South American city can price at exactly the same mileage as a simple round trip. It turns a Peru trip into a Peru-plus-Argentina trip for nothing.

What I would not do is transfer Chase points speculatively to United hoping to find business class availability at 60,000 miles later. The saver space on Polaris to Lima is real but tight, and Chase points sitting in your Ultimate Rewards account can also flow to Aeroplan or Air Canada — which brings us to the next section.

Avianca LifeMiles: the value pick if you can find Star Alliance availability

Avianca is Colombia’s flag carrier, and its home territory means excellent availability, with flights to Colombia from the US starting at 16,000 LifeMiles one-way in economy. Peru sits right next door and prices similarly on the partner chart — expect economy in the 20,000 to 25,000 range one-way and Star Alliance business class in the 45,000 to 55,000 range on many gateways, subject to the caveat that LifeMiles uses an unpublished region-based award chart for Star Alliance partner flights and pricing has become more variable after a series of 2024 and 2025 devaluations.

The single biggest structural reason to use LifeMiles for a US–Lima booking is that LifeMiles charges zero fuel surcharges on all partner airline redemptions. That does not matter much on a United flight, but it matters a lot on the routings LifeMiles opens up: Avianca via Bogotá (great connection times), Copa via Panama City, or United from any Star Alliance gateway. On a partner award you are paying $30 to $80 in real taxes, not $300 in carrier-imposed fees.

LifeMiles is also the easiest of the four programs to accumulate on the fly. It transfers 1:1 from Amex Membership Rewards, Citi ThankYou, Capital One and Bilt, and Capital One in particular has run transfer bonuses to Avianca as high as 15%, which brings a 53,600-mile award down to roughly 46,600 Capital One miles when a promotion is live. I always check the current transfer bonus tracker before moving any points to LifeMiles — a 15% Capital One bonus on a Star Alliance business class seat to South America is one of the better redemptions on the board when it hits.

Two warnings worth taking seriously. First, LifeMiles expire after just 12 months of inactivity unless you’re a LifeMiles+ subscriber, so keep points in a transferable currency until you have a specific booking to make rather than transferring speculatively. Second, LifeMiles’ award search tool does not always display the same Star Alliance space that Aeroplan or United show — always confirm availability on a second Star Alliance program’s search before you pull the trigger on a transfer.

Air Canada Aeroplan: still the most flexible Star Alliance chart, and unchanged for Peru

Aeroplan devalued its chart on June 1, 2026 — and if you were paying attention to the transatlantic and transpacific numbers, it stung. But there is one very specific piece of good news for anyone flying to Peru: five zone combinations are completely unchanged, including within North America, within South America, and North America to South America. The Lima routing pays what it used to.

Aeroplan prices partner awards by the zones you’re flying between and the actual distance flown. Miami to Lima is roughly 2,620 miles, and most US-East-Coast-to-Lima routings fall inside the 0–2,500 or 2,501–5,000 mile band once you factor in connections. In practical terms, expect roughly 25,000 to 40,000 Aeroplan points one-way in economy and 45,000 to 60,000 in business class on Star Alliance partners like Copa, United or Avianca. Air Canada’s own metal to Lima connects through Toronto and uses dynamic pricing, so I would not chase it.

What makes Aeroplan uniquely useful for this trip is the free stopover. Stopovers are still 5,000 points, one of Aeroplan’s best features — you can add a stopover on a one-way award for just 5,000 extra points. That opens up itineraries like New York to Panama (stopover for a few days) to Lima for 5,000 points on top of the base fare, which is a ridiculously cheap way to see two countries on one ticket. Nobody else in Star Alliance does this on partner awards.

Aeroplan also has the most transfer partners of any airline program — Amex, Chase, Capital One and Bilt all transfer 1:1 — which means it is often the easiest way to burn Chase Ultimate Rewards on a Star Alliance seat. If your points balance is not quite where the trip needs to be, Roame is worth running before you commit to any single program — it scans 25 programs at once across a full 365-day calendar, and on a route with this many Star Alliance carriers it often surfaces the same physical seat priced very differently across LifeMiles, Aeroplan and United.

The head-to-head, in one table

Program	Economy one-way	Business one-way	Best gateways	Fuel surcharges
AAdvantage (AA metal)	~13,500–30,000 (dynamic; sales hit low end)	~27,500–60,000 (dynamic; sales hit low end)	MIA, DFW (nonstop)	Low
United MileagePlus (own metal)	~30,000–45,000 saver, higher standard	~60,000+ Polaris when saver opens	IAH, EWR (nonstop)	Low
Avianca LifeMiles (Star Alliance partners)	~20,000–25,000	~45,000–55,000	Any Star Alliance city via BOG, PTY, IAH, EWR	None on partners
Aeroplan (Star Alliance partners)	~25,000–40,000	~45,000–60,000	Any Star Alliance city; stopover for +5,000 pts	Low; partner booking fee applies

A note on how to read that table: the AAdvantage and United numbers include their full dynamic range because you cannot count on a saver price, while the LifeMiles and Aeroplan bands reflect real observed partner pricing on this specific route. In practice, on any given search, the cheapest way to a US–Lima seat is whichever Star Alliance program has correctly loaded space for the exact partner you want to fly, and running the same date across United’s search, LifeMiles’ search and Aeroplan.com will usually turn up meaningful differences on identical metal.

The Lima–Cusco leg: do not burn miles on it

Almost every reader flying to Lima on points is doing it as the front half of a Machu Picchu or Sacred Valley trip, which means the Lima–Cusco domestic hop is unavoidable. This is where I see people waste points badly. LATAM, Sky Airline and JetSMART all operate multiple daily nonstops between LIM and CUZ, the flight is about 90 minutes, and cash fares typically run $50 to $100 one-way. Book it on cash and use your points on the international segment.

There are two exceptions. If you are already booking through United and can add Lima–Cusco as an Excursionist Perk segment on the same PNR, it costs zero additional miles and is worth doing purely for the operational simplicity of one ticket. And if AAdvantage has the JetSMART or LATAM award loaded — AAdvantage added JetSMART as a bookable partner in November 2025 — it can occasionally price at just a few thousand miles when added to the international itinerary. Anything that requires transferring points specifically to cover this leg is a losing trade.

One altitude warning that matters for your planning: Cusco sits at over 11,000 feet. If you can arrange your itinerary so that you fly Lima–Cusco, spend the first night or two in the Sacred Valley (at around 9,500 feet) instead of Cusco proper, and then work up to the city later, you’ll dodge the worst of the altitude adjustment. This has nothing to do with your points strategy, but it will affect how much of the trip you actually enjoy.

Delta, Copa and the also-rans worth naming

Delta flies nonstop from Atlanta to Lima and added a seasonal Salt Lake City route in late 2025. SkyMiles is fully dynamic with no published chart, and pricing on this route is not competitive with any of the four programs above — I would not build a strategy around it. But if you already have SkyMiles sitting in your account and cannot get Star Alliance space to line up, watch Delta’s award calendar for occasional flash prices on the ATL–LIM run.

Copa’s own program, ConnectMiles, does not partner with any of the major US transferable currencies, so it is largely irrelevant unless you happen to hold Marriott Bonvoy points at 3:1. What is very relevant is that Copa flights from the US to South America via Panama can be booked for around 55,000 miles one-way in business class on the Aeroplan chart, and Copa’s Panama hub is genuinely convenient for anyone flying from the East Coast — connection times of under an hour are common. Aeroplan and LifeMiles are the smart ways to book Copa metal.

British Airways Avios is worth a mention only because it can, at the right distance band, price the Miami–Lima LATAM segment at a favorable rate. LATAM is not in oneworld but has a partnership with BA for redemptions on select routes. Availability is thin and the math is fiddly enough that I’d only bother if you already have a large Avios balance and are avoiding transfers.

Booking strategy: what I’d actually do

The honest ordered playbook, in the sequence I’d try them:

1. Search AAdvantage first if Miami or Dallas is a reasonable gateway. If a business class seat prices at or near 27,500 miles, book it and move on — that is the ceiling for this route.
2. If AA is not cooperating, run the same dates on united.com. Look for saver economy under 35,000 miles and Polaris business under 70,000. Log in as a cardholder if you have a United card, since the discount changes the price on the screen.
3. Cross-check any United-operated saver space against LifeMiles and Aeroplan pricing. On the exact same flight, one of the two often prices meaningfully cheaper — and neither passes the fuel surcharges that other Star Alliance programs might load.
4. If you’re on the East Coast and Copa’s timing works, pull Aeroplan or LifeMiles for the Panama routing. Copa’s lie-flat business class is not the same product as AA’s premium cabin from Miami to Europe, but for a five-hour flight to Lima it more than does the job.
5. Only after all four programs come up dry do I look at Delta or the cash rate. For cash-and-points hybrids or off-cycle dates, comparing to flights out of LA or Miami departures is worth a minute before you commit.

One more tactical note. Award availability on this route is best three to six months out for peak season (June–August) and roughly one to three months out for shoulder season (April–May and September–October). Last-minute Polaris and AA business seats do release inside two weeks of departure with some regularity, and Seats.aero’s alert function is genuinely useful for catching those — you set the parameters and let the notifications come to you rather than refreshing five different award search tools yourself.

Cash rate reality check

Points redemptions only make sense when they beat the cash price. Round-trip economy from major US gateways to Lima typically clears $450 to $750 in shoulder season and $700 to $1,100 in peak. Business class round trip on American, LATAM or Delta hovers around $1,800 to $2,800 outside of holiday demand. Do the math: 55,000 miles for a round-trip economy seat at $600 is 1.1 cents per point — below what I’d pay for any of these currencies. But 55,000 miles for a business class ticket priced at $2,200 in cash is 4 cents per point, which is genuinely excellent.

This is the rule I’d tell anyone using points for the first time on this route: use miles for the premium cabin, use cash for the economy leg. Award value on business class to Lima is one of the strongest sweet spots left in the Americas. Award value on economy is fine but not exceptional, and Peru is one of the destinations where staying flexible with cash bookings sometimes wins. That extends to lodging too — before you commit to a hotel points strategy in Lima or Cusco, run the cash rates for the same nights. Independent boutiques in Miraflores and Barranco often beat any point redemption on a per-night basis.

Frequently Asked Questions

What’s the single cheapest way to fly to Lima on points from the US?

When AAdvantage runs a targeted sale, business class seats have priced at 27,500 miles one-way on the Miami–Lima or Dallas–Lima nonstop, which is the ceiling for value on this route. Outside of those sales, LifeMiles on a Star Alliance partner (Copa via Panama or United nonstop) usually prices business class in the 45,000–55,000 range one-way with no fuel surcharges — the most consistent value.

Do I need a visa to visit Peru as a US citizen?

No. U.S. citizens receive visa-free entry on arrival, typically granted for 90 days, provided the passport is valid at least six months beyond the arrival date. There is no pre-arrival form or health paperwork required in 2026.

Should I use points for the Lima–Cusco domestic flight?

No, cash is almost always the right answer. LATAM, Sky Airline and JetSMART operate the route multiple times daily, and one-way fares typically run $50 to $100. Save your points for the international segment. The only exception is if you can add the segment for free using United’s Excursionist Perk on a round-trip international award.

Was Peru affected by the 2026 Aeroplan devaluation?

No. All four zone combinations involving South America stayed exactly where they were on the June 1, 2026 chart update — including North America to South America. If your redemption is to Lima or anywhere else in South America on the Aeroplan partner chart, the pricing did not change.

Can I book LATAM flights to Lima with any US-issued transferable points?

Not directly, but there is a workaround. Delta SkyMiles can book LATAM as a codeshare partner, and British Airways Avios can price LATAM flights on a distance-based partner chart. Neither is your first option for value, but if you want to fly LATAM’s lie-flat 767 out of Miami, those are the two paths.

Do LifeMiles really charge zero fuel surcharges on partner awards?

Yes. This is the program’s single biggest structural advantage. On a Star Alliance partner award booked through LifeMiles, you pay only actual government taxes and airport fees — typically $30 to $80 total on a US–Lima ticket, compared to hundreds of dollars in carrier-imposed surcharges you might see on the same routing through other programs. Just be mindful that LifeMiles expire after 12 months of inactivity without a LifeMiles+ subscription.

Which credit card gives me the most flexibility for booking Lima?

Capital One Venture X hits three of the four programs discussed in this article — Aeroplan, LifeMiles and Air Canada — at 1:1. Amex Membership Rewards hits Aeroplan, LifeMiles and Delta. Chase Ultimate Rewards hits Aeroplan and United. If you can only carry one card, Capital One or Amex give you the most program flexibility for this specific route.

Bottom Line

Lima is one of the few destinations where all three major alliances actually compete, and that means the “best” program is the one whose chart aligns with the gateway you can reach and the cabin you want to sit in. If you’re near Miami or Dallas, AAdvantage on AA metal is hard to beat — especially on a targeted sale, where 27,500 miles for lie-flat business class is the ceiling. If you’re anywhere else and open to Star Alliance connections, LifeMiles and Aeroplan will consistently beat United’s own dynamic pricing on the exact same partner flights, and Aeroplan’s 5,000-point stopover in Panama or Bogotá turns a Lima trip into two countries for almost nothing. Skip the Lima–Cusco flight on points, book it on cash, and save your miles for the piece that actually delivers outsized value: a business class seat across the Americas.
