How To Change Name On WestJet Airlines Go to the official WestJet website or get in touch with customer support to modify your name on a ticket issued by the airline. Go into your account, pick the reservation that needs to have its name changed, and then browse to the "Manage Trips" area. To change the passenger details, adhere to the suggestions. If you made your reservation through a travel agency, ask for help from them directly. Be ready to present the required paperwork to back up your request for a name change, such as a marriage license or court decree. Changes should be made well in advance of your flight, as fees may apply.
