Many visitor airfares limit you to one stop in each destination city. In most cases, however, you're allowed to connect through the sponsoring line's hub as often as required. Validity periods are measured from the date of a ticket's first use, not its purchase date.
Air Passes In order to promote tourism in their countries, national airlines offer air passes at reduced rates to tourists. If you are planning to travel extensively in a country or region, an air pass may prove most cost effective. But before you do purchase an air pass, get an idea of the cost of the individual flights you want to take. Also look at adding stopovers on your international ticket, it may prove cheaper.
All passes must be purchased from a travel agent or airline outside the country you are visiting. Some are only available for purchase in the U.S. to U.S. residents. Most require a planned itinerary with confirmed flights when you purchase an air pass. Ask about children's discounts as well. A good website we recommend for air passes is MISA Travel.
TIP: Always price individual tickets for your itinerary before you buy a pass--they're often cheaper.
