Is it correct to say "He is good with flying to Europe"? [closed]

"To be good with (something)" is very colloquial for "to find (something) acceptable or satisfactory", "to be satisfied with (something)". I think it's a fairly recent idiom, and I don't know how broadly used it is; I'm in the U.S. It's used correctly in your sentence, as long as such casual language is appropriate for the context.

So, "He is good with flying to Europe" means essentially that flying to Europe is fine with him.

Also: "Would you like another drink, sir?" "No, thanks, I'm good," meaning one is satisfied, has had one's fill.
