My cats had to travel via airplane since I was going to be doing a lot of travel with work. They flew from the east coast to the west coast. My anxiety cat was just as he was before, kept quiet but no accidents this time!
My other one is like yours, definitely a screamer. But he got all his screaming out of the way on the car ride to the airport. He made a little bit of noise while my parents were checking in but they told me he was very well behaved on the flight.
Now all cats are different, so it’s impossible to tell. But honestly I tell myself that if we can survive screaming babies and kids on a flight, then a cat who lets out a cry every few minutes should be nothing
