As Roger said, I think this is the perfect time for a chromogenic film like XP2. Unless you need to push past 800, I think it's your best bet for using the film cameras you want and avoiding the hassle of developing or airport security.
Incidentally, I've never had a problem getting a hand check at US airports. If they ask you the speed you can just say that you push to 3200. I have no knowledge of Israeli airports, though.
