Details
From the project READMECabin Codes
When reading Seats.aero results or discussing award inventory, these cabin codes appear:
| Code | Cabin | Notes |
|---|---|---|
| F | First Class | Includes true first class suites |
| J | Business Class | Lie-flat seats on long-haul |
| W | Premium Economy | Also sometimes coded as "P" |
| Y | Economy | Standard seating |
Fare Class Codes for Saver Awards
These are critical for partner bookings. If you see these fare codes available on united.com (or equivalent), the flight is bookable through partner programs at their (often lower) rates.
| Code | Meaning | Programs That Use It |
|---|---|---|
| X | Economy Saver | United MileagePlus, bookable through partners |
| I | Business Saver | United MileagePlus, bookable through Turkish M&S and others |
| O | First Saver | United MileagePlus |
Why This Matters
Partner award rates are often dramatically lower than the operating airline's own rates. United business saver (I class) bookable through Turkish Miles&Smiles is a classic example: a route that costs 80,000 United miles might only cost 45,000 Turkish miles. But Turkish (and other partners) only sees the saver inventory. If only "standard" or "everyday" fares show on united.com, partners cannot book that flight.
When checking award availability for a flight you found on a partner program (Turkish, Aeroplan, ANA, etc.), verify the saver class is open on the operating airline's site before transferring points.
