Q. If one is travelling on an aeroplane whilst fasting, when does one break the fast?
A. If one is fasting whilst airborne and it is the time to break the fast, one must break the fast on the aero plane at sunset according to the time zone of the area one is flying over. This may be done by observing the sunset from the window of the aircraft and breaking the fast. There are many Islamic mobile apps through which one can easily determine the correct fasting timings of any zone around the world.
It should be noted that it is not compulsory for a person to fast in Ramadaan whilst travelling a distance of 78 Kms or more. If while travelling in Ramadaan, one did not fast, one will have to make up for the missed fast later.
Allah Ta’ala Knows Best
