Your Frequent Flyer Number is the unique identifier for your airline loyalty account. Adding it to flight bookings ensures you earn miles/points and tracks progress toward elite status tiers. Crucially, it’s distinct from your ticket number or booking reference—think of it as your exclusive rewards "membership ID."

- Unlock perks:
✓ Priority boarding & preferred seating

Using Your Frequent Flyer Number on Trip.com
Enter your number during checkout to:
- Automatically credit miles to your airline account (for eligible fares).
- Earn Trip Coins after trip completion—redeemable for future discounts.
How to Get My Frequent Flyer Number
- Select a program aligned with your travel habits—typically the airline you fly most or an alliance you prefer.
- Sign up directly on the airline’s website or app to receive your Frequent Flyer Number instantly.
- Begin adding it to every booking. A smart approach is to join a program within your most-used alliance (Star Alliance, SkyTeam, or Oneworld), allowing you to earn miles across multiple airlines with one number.
💡 Tip: If you're unsure, base your decision on the airline you fly most frequently. Elite status and miles earned are usually recognized across all partners within the same alliance. Not sure which to pick? Review your common routes and see which airline alliance dominates those flights.

Frequent Flyer Number FAQs
Is a frequent flyer number the same as loyalty number?
Yes, airlines use different terms, but it's the same unique ID you use to earn and redeem.Can I use my frequent flyer number for someone else's ticket?
No. Each traveler earns to their own account. Some programs allow family pooling or point transfers, but your number itself is personal.

The number typically doesn't expire. Miles/points may expire due to program rules unless you keep activity going (varies by airline). Some U.S. programs pause mileage expiry if you hold and keep active a co-branded credit card or have any qualifying earn/redeem activity within a set window—check your program's policy.Can I add a frequent flyer number after booking?
Usually yes, via online check-in or at the airport. If you forget entirely, many programs allow retroactive credit for flights flown in the past few months—submit a missing-miles claim with your ticket number and boarding pass.
