Praying On The Plane
When we buy a plane ticket, we are obligated by the terms and conditions to abide by the airline rules. If the airline doesn’t allow standing up while praying then we should sit and pray. If there’s difficulty in determining the salah time due to the time difference, one can do a personal ijtihad to pray at a more suitable time. However, I find it unnecessary. We can always pray according to our departure or destination time zone.
