How Should A Person Traveling By Plane Break His Her Fast?

How should a person traveling by plane break his/her fast?

Those who travel need to determine imsak and iftar according to the place they are in at that moment. Those who travel by plane while fasting should determine the time of imsak and iftar according to the place over which the plane is at the time. However, if one is traveling an inter-continental travel by a very fast plane, the time between imsak and iftar can be excessively short or long. In this situation, the person who will travel may leave the fast for qada. However if one has already started to fast, then s/he may make iftar by making comparison, e.g. according to the iftar time of where s/he started to fast.
