How can I pray on the plane if I am travelling oversees?
There is no specific answer for this question nevertheless I would say that if the conditions is good in the plane it is better to pray standing but it is not required to face Qibla. Maybe when starting the prayer the person faces Qibla and if the plane changes its position it is not necessary to turn while praying. However, if praying standing would be problem in the plane it is permissible to pray sitting at seat. in this case, there is no need to turn the Qibla
