 This guide gives a decision framework for Costa Rica dry-season 2026 award flights to San Jose or Liberia.

 It requires a same-week live pricing check across Star Alliance and oneworld before any points are transferred.

## How dry season award space works

 For Costa Rica's December–April 2026 dry season, the two airports that decide this comparison are San Jose (SJO) and Liberia (LIR). Alliance membership belongs to the carrier, not the route: United and Avianca are Star Alliance carriers, while American, British Airways, and Iberia are oneworld carriers. Use that mapping as your starting list, then verify which of those carriers actually publish service to SJO or LIR in your travel month.

| Carrier | Alliance | What to verify for SJO/LIR |
| --- | --- | --- |
| United | Star Alliance | Nonstop service from its US hubs to SJO; any LIR service in your month |
| Avianca | Star Alliance | SJO via San Salvador; any LIR service in your month |
| American | oneworld | SJO from Miami or Dallas; any LIR service in your month |
| British Airways / Iberia | oneworld | Whether either publishes SJO or LIR service for your month |

 At SJO, the Star-side options named in this comparison are United nonstop from its US hubs and Avianca via San Salvador; the oneworld-side option named is American from Miami or Dallas. Because schedules change seasonally, open each carrier's own route map and confirm the nonstop before pricing; a route that appears in one month may not appear in another.

 LIR has thinner international service than SJO, so the first check is whether your alliance's carriers fly there nonstop at all in your travel month. If they do not, connecting through SJO adds a separate domestic hop, and that hop can break award ticketing when the international award and the domestic segment cannot be combined on one ticket. A 12go.asia listing shows San Jose–Liberia flights between RUB 9,725 and RUB 24,261, but it does not state whether those amounts are one-way or round-trip, so price that hop in the same booking flow rather than assuming its cost.

 Dry-season award space should be treated as a live result for your exact week, not as a fixed inventory chart. Search the identical dates on both alliances' programs, then compare the cash fare for those same dates; the better path can change from one week to the next. Do not transfer points until that live comparison shows which redemption costs fewer cents per point after surcharges and taxes, or whether the cash fare is the lower-cost choice.

 For award purposes, the practical question is not whether an alliance serves Costa Rica in general, but whether it serves your airport on your dates with combinable segments. A Star itinerary that requires a separate domestic ticket, or an oneworld itinerary that lacks a nonstop to LIR, may be unusable even if the alliance has a presence in the country.

## The evidence you must gather first

 This section prescribes the three-source cross-check that every later number depends on: before transferring any points, price the identical dates in a live booking flow on both alliances' programs, then compare the redemption with the cash fare. The check has three parts—carrier award pricing, transfer-partner availability and ratios, and a same-week cash baseline—and all three must be recorded from live pages, not from memory or a saved chart.

| Source | Live check | Record |
| --- | --- | --- |
| Carrier booking flow | Identical dates as an award on United.com and on AA.com or ba.com | Miles quoted; taxes and carrier surcharges; one-way or round-trip label |
| Transfer pipeline | The credit-card program's own transfer page | Transferable currencies; current ratio; any fee or bonus shown |
| Cash baseline | Same-week cash fare in the same cabin | Fare, taxes, and fees separately; one-way or round-trip label |

 Source one is the carrier booking flow. Search the identical dates as an award on United.com for the Star Alliance side and on AA.com or ba.com for the oneworld side. Record the miles quoted and the taxes and carrier surcharges for each result, and label every figure one-way or round-trip so a one-way award is never compared with a round-trip cash fare. If one flow returns no award space, record that as the result for that program rather than substituting a different date or route.

 Source two is the transfer pipeline. On the credit-card program's own transfer page, confirm which currencies actually transfer to each airline program you are considering and the current transfer ratio. Do not assume a ratio from a prior year, and do not treat a program as available unless it is listed on that page. Record the exact currency, program, and ratio shown, plus any fee or bonus stated there.

 Source three is the cash baseline. Pull the same-week cash fare for the same cabin and the same or nearest comparable itinerary, then separate the fare from taxes and fees. Label it one-way or round-trip to match the award records. This cash figure is the benchmark against which the award's cents-per-point value is measured after surcharges are added to the award side.

 Only after all three sources are recorded should you calculate which option costs fewer cents per point after surcharges, or whether the cash fare wins. If any source is incomplete, stop and do not transfer points; a partial cross-check is not evidence. The decision belongs to the recorded numbers from that week, not to a static alliance chart.

## Star vs oneworld compared

 This section presents the comparison framework whose winner is decided by your own recorded numbers, not asserted upfront. Enter the cash fare, award taxes and surcharges, mileage price, and elapsed time you recorded for each alliance, then let those figures choose; no static chart can settle the comparison because the inputs move with date, cabin, and routing.

 Score each program with one formula and one unit convention: (cash fare minus the taxes and surcharges you would pay on the award) divided by miles required, then multiplied by 100 to express cents per point. Run every figure as round-trip or every figure as one-way; never mix a round-trip cash fare with one-way miles, or a one-way surcharge with a round-trip fare. Mixing units is the most common way this comparison goes wrong.

 Compare nonstop and connecting routings in separate columns. A connection can lower the mileage while adding hours, so price both the miles and total travel time before choosing; do not treat a lower-mileage connection as better unless you accept its time cost.

 The winner rule is the alliance whose live quote has the higher cents per point and actual bookable space on the itinerary and dates you priced. If the higher quote lacks bookable space, the bookable quote with the next-highest cents per point wins; if neither has space, neither redemption is available on those terms.

 Price both alliances in the same booking week, using the same dates, cabin, passenger count, and baggage assumptions. A fare or award change between quotes can make one alliance look better for reasons unrelated to the program.

 Record the outcome as a decision note: alliance, routing type, cents per point, bookable status, and whether cash won. That note is the only defensible basis for transferring points, because it preserves the comparison after prices move; if the winning redemption's cents per point is below your personal transfer threshold, or if cash is cheaper after surcharges, pay cash instead of transferring points.

## Numbers that decide the booking

 The decision is made at the line-item level, not by the headline award price. Before any transfer, record three separate figures from the live booking flow for each alliance: the booking class, the carrier-imposed surcharge, and the tax line. Treat them as independent checks; a change in any one can reverse which option is cheaper. Do not transfer points until the three lines have been compared with the cash fare.

 Checkpoint 1 — fare class. Note the booking class shown in the award results, not just the mileage price. Saver-level space books into specific classes, while broader-availability quotes can price far higher for the same flight. Confirm which class you are actually buying; "available" is not the same as saver-level.

 Checkpoint 2 — surcharges. Record the carrier-imposed surcharge line separately from taxes. Some oneworld partners add large surcharges that can flip the winner, and this is the line item where the comparison is usually lost. If you fold it into taxes, the cents-per-point comparison becomes meaningless.

 Checkpoint 3 — tax line. Record taxes and government or airport charges on their own line. They are not carrier surcharges, and they may apply differently to an award than to a cash fare. Keeping them separate prevents you from crediting or blaming the wrong program for a charge you would pay either way.

| Checkpoint | Record | Why it can flip the winner |
| --- | --- | --- |
| Fare class | Booking class shown in award results | Saver and broader-availability quotes can price very differently |
| Carrier surcharge | Carrier-imposed surcharge line only | Partner surcharges can erase an apparent points advantage |
| Tax line | Taxes and airport charges separately | Mixing taxes with surcharges distorts cents-per-point |

 Cost of being wrong. Booking the wrong alliance can leave you with a higher award price for the same seat, points transferred into a program you cannot reverse, and surcharges that are not recoverable. The error is usually visible only after the transfer posts, so the three checkpoints are the last chance to catch it. If the redemption does not beat the cash fare on those terms, keep the points.

## And checklist

 Use this arithmetic to turn live quotes into one comparable number. Keep every figure tied to the same round-trip dates and the same cabin, and label taxes and surcharges separately from the fare: net value equals the cash fare minus the taxes and surcharges you would pay on the award, then divide that net value by the miles required to get value per mile. Enter only figures from your own live quotes.
