Plus UAL also doesn’t have any remaining 747-200s.
There’s also NWA31, which usually an EGKK flight-
As well as UAL0, which isnt a valid flight number AFAIK.
And on this page- http://flightaware.com/live/airport/KBLH/departures note how all the B747 flights at the bottom all leave at the exact same time, Thursday at 12:38 am.
Also does anyone know if the arrival and departure airports are even 747 capable? I think KIWA is but I don’t know about the others.
There’s a system glitch here methinks, but I don’t know. This is proving to be interesting!
Edit to reply to lancasterperch-
As far as I know, none of AA’s 747s are even able to fly, they’ve probably all been scrapped by now or are with other carriers. Also I still am not convinced these are transfer flights because those usually use 9*** as their flight number, not something like NWA31 or UAL1 which is usually assigned to a regular flight already. Plus there’s UAL0, the weird flight number.
