Destination airlines Bug

Airport: Dulles [IAD]
Destination: Hong Kong
Type of aircraft: X

On this destination airlines can independently substitute themselves. After each 3-4 entering the game “Air China” flight can be changed “UPS” and vice versa.
So, we can have duplicate flight.

Any update on this bug?

I’m having the same issue. This one is at PRG. It’s not normally an issue unless I’m expecting two cargo arrivals, not two passenger arrivals.
