Booking British Airways fares as a travel agent
Travel agents book British Airways fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live BA fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. British Airways results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
