How B3 appears in a PNR
In an Amadeus, Sabre, Galileo or Worldspan flight segment the two-character airline code comes first, directly before the flight number, so every flight sold under this code starts with B3. Codeshare flights carry the marketing airline's code, so the airline operating the aircraft can be a different one. Paste a PNR into the free PNR converter and B3 is shown as Bhutan Airlines with its logo, next to local times and the true flight duration.
