At what point in time were parachutes stopped being considered cowardly?

I know that WWI showed some use of parachutes, but I was always under the impression that the “chivalrous fight in the sky” which was considered almost like a gentlemen sport in a way, that they thought of using a parachute as a cowardly act and not that of heroism and hence did not often carry them. What did WWII aces and fighter pilots think of battle in the sky? Did air combat loose that chivalrous feeling? When did parachuting stop being considered cowardly? In WWI, somewhere between two wars or during WWII? Thanks guys! Love the show. And LOVE Indy!! :smiley:
