You can add baggage to your ticket after purchase. You’ll need your booking code or ticket number, last name of the passenger, and the email address specified in the booking.
Contact the ticket carrier and ask to include baggage. You can find the carrier’s name in your ticket. Adding baggage in advance is usually cheaper than at the airport.
