Yes, you can usually change your passport number after booking, but it may depend on the airline’s policy and timing:
- Before Check-In: If your flight is a while away and you haven't checked in, you can typically update your passport details through the airline’s website, app, or by contacting customer support. Most airlines allow this if you’ve renewed your passport or made an error.
- After Check-In: If you've already checked in, updating details may require cancelling the check-in and re-doing it with the new passport details. This might involve additional fees or require support from customer service.
- Fees and Restrictions: Changing your passport number is often free if done early, but some airlines may charge a fee, especially closer to departure. Check with the airline’s policy on Trip.com or contact their customer service for guidance.
