All too often the joy of flying and traveling is overshadowed by just how expensive it is to do so. However, some airlines offer flight passes, enabling passengers not to fret about the cost. Some flight passes offer free flights to all destinations served by the airline for a set annual fee (typically excluding taxes and fees), while others, like Air Canada's Home Away From Home Flight Pass, offer package discounts on set routes. There are far too many airlines worldwide to mention here (e.g., Air Tahiti and Japan's Starflyer also offer flight passes), but here are some to consider in the United States, Canada, and abroad.
