How X3 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 X3. 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 X3 is shown as TUI fly Deutschland with its logo, next to local times and the true flight duration.
