Once your flights have been confirmed and, where applicable, tickets have been issued, your airline confirmation code (PNR) will be added to your flight voucher (available in your Passenger Portal). Using this code, you can manage your booking via the airline’s website to view and add baggage options.

Example: 

easyJet.com -> 'Manage Bookings' -> 'Find Booking' (do NOT sign in ) -> Enter your airline confirmation code and your surname.
