You can add baggage, seat selection, meal service, and other in-flight amenities to your booking.
For most flights, you can simply copy your airline confirmation code and head to the airline's website or mobile app to select these extras.
Please note that these services are provided at the discretion of the airline and may not be available on your particular flight. Every airline’s carry-on and checked-baggage policies are different, and fees may apply. Additionally, advanced seat selection is not available on all airlines.
