Answered by Shaykh Ilyas Patel
How one can manage his fasting during traveling by air through diffrent time zones. I start a fast in one time zone and when I reach a place by air that time zone is having earlier sunset? Similiarly traveling towards west one may have length his fast? What a person do while in plane? Should he break fast for time of orgin or time of destination. Also If a person goes to a place where there is Eid one day early and he may end up having 28 siyams (fasts). Or may be enging up 31 siyam (fasts). What one should do in these situations
In the Name of Allah, Most Compassionate, Most Merciful
One will follow the time zone of the destination as this is what one is commanded to follow in that moment and time.
If a person goes to a place where there is Eid one day early, then one will follow the destination zone and keep the 29th day fast on another day.
And Allah Knows Best
