Former JAS, JAA, JTA, JAC, JAL Express and even JALways, why don't they all operate as JL flight numbers?
I guess JAA still might have some political reason to operate flights from Japan into Taiwan (TPE and KHH). JALways might be used for charter and holiday destination flights ex Japan to destinations such as HNL, GUM, BKK etc.
But why does JAC, JTA and JAS still operate under IATA code NU, JD and 3X and not JL? I mean some JAC and JAS planes already got the JAL livery but still operate under separate code. Is there any particular reason? Is this going to be changed soon?
