Love to visit far off places, but hate having to get there? Travel experts have some tips for making your long flights a little less miserable. Seat selection is extremely important when you’re in the air for hours on end. Book an aisle seat so you can more easily stretch your legs or even better, make the upgrade to the extra legroom seating.
