Popa,
You are wrong about flying on Shabbos.
I once asked my Rav about this. I was flying to Japan and curious if it would be possible (we wouldn’t actually consider doing it, but I thought it was interesting).
He said you have to be on the plane before Shabbos. Once you are on the plane, you are allowed to stay on until the plane lands. You are even allowed to disembark and take your luggage off the plane. Once you get to your destination, you are not allowed to leave the airport until Shabbos is over.
He did say its not hashkafically preferable.
Not every Rav may pasken this way, but its not a “You are NOT allowed to fly on Shabbos” ruling across the board.
