If anyone travels to distance going and coming minimum 44 km and his intention is stay to his travel destination is less than 10 days then his salat will be shortened and he will not fast their in those days.
Now if he start his travel after Zohr salat to a place with all above conditions he will have to complete his fast of that day doesnt matter when he will arrive to his destination and if he moves from that place to his watan ( where is is living) after Fajr salat and will reach there before Zohr salat then he will fast on that day.
