Delta Vacations is extending its "More for 4" incentive to the end of May. Under this program, agencies earn one free airline ticket each time they book four air-inclusive Delta Vacations packages with a minimum four-night stay. Group bookings of 20 or more passengers also qualify. Reservations must be made by May 31 for travel completed by December 15. Visit [www.vaxvacationaccess.com].
