For short-haul flights, you may be able to pre-book your seats directly with your airline, when we supply you with your flight reference number (there may be a charge for doing this). If we haven’t provided you with this, it will be available when we send you your final travel documents, approx 7-10 days before your departure date. For long-haul flights, if you are in economy they cannot be pre-booked until at least 6 weeks before departure – most airlines will charge for this unless a higher class. We cannot do this for you and must be done directly with the airline.
