The ruling on one who prays with gestures while being able to bow and prostrate in an airplane

A person prayed in the airplane with gestures, and he was able to bow and prostrate. Does he have to repeat the prayer, or what? And is he excused due to his ignorance?
He has to repeat the prayer as long as he was able to do so and did not, because bowing and prostrating are pillars.
As for commands, they are not dropped due to ignorance, and he should have asked. Then, if he was able to get off at the airport before the time ended, why did he not delay?
