Prayer of those who are waiting to depart or just arriving

If the airport, sea-port or railway station are within the outskirts of the traveler’s home-town, or even linked to his/her home-town by contiguous dwellings or buildings, no license to shorten prayers is allowed, since he/she would not be considered to have departed the dwelling or town. Once the plane, ship, or train has traveled away from all housing and buildings, only then is he/she allowed to shorten and/or perform together two prayers. If the airport, harbor, or train station is outside the home town, a traveler is allowed to utilize the license to shorten and combine two prayers together based on the fact that he or she in this case has departed from his/her city and has already commenced on his/her journey.
