Fly UPS to Mexico

United Parcel Service (UPS), known for delivering parcels, has added a new service. It's converted some of its air cargo space to airline seats -- seats that UPS is touting as having more leg room than most passenger planes. These seats are being sold to tour operators, who are selling the flights 20 to 40 percent cheaper than normal airline tickets.

This season, flights are running only up to August 8, but the program is expected to fly again next year. Try your travel agent to see if flights are available from your departure city. Vacation Expres (800-848-8047) is selling seats to Cancun (a short ferry ride to Cozumel) from several key cities.
