I had a concern because the trip was supposed to end on 6/27/14. The trip operator made such a mess of the airline reservations that I didn't arrive home until 6/28/14, one day after my policy expired since I purchased it for the stated duration of the trip. Perhaps you could advise clients to add one day beyond the stated end of trip to their policy period so coverage would continue if they don't actually get home on the end of trip date.
