I've stolen a jet in the story mode (multiple times now). I've brought it to both hangars (red squares on the picture), but none was saved by the game.
I tried both hangars with Franklin and the one more in the south with Trevor.
Has storing jets been fixed or did I miss something? If I drive into the hangar, nothing happens. If I leave the jet, stay right next to it, save and reload, it will be gone.
I'm playing on PC.
