I don't know about "arbitrary" but most of my travel I book with something like Expedia ends up being split across carriers without using codeshare numbers. E.g. over Christmas I visited my parents in Australia and the domestic leg to Tokyo was a JL flight number, and international leg was a QF flight number, both on the same itinerary/using the same confirmation code.
- lxgr 2y agoA CRS/GDS locator (PNR, the 6-digit alphanumeric code often used to identify tickets, but really only points to a GDSs database entry) and a ticket are not the same thing, though. A PNR can include non-air travel segments like hotels and rental cars too, for example. That's something very different from a single airline issuing a ticket for a complete itinerary, which importantly makes them responsible for getting you to your final destination in case of missed connections, checking your baggage through etc. If you still have the confirmations or boarding passes, you could check for the three-digit numeric e-ticket number prefix, which defines which carrier actually issued the ticket.
- kalleboo 2y agoThere was a single ticket number for the itinerary, starting with 081 (Qantas)
- Dalewyn 2y agoJAL (JL) and Quantas (QF) are both members of Oneworld, so they can share itineraries (and things like frequent flyer status and fare class) in a single booking regardless of codeshare.
