Think of an air pass as a book of bus tickets that you rip off one by one and give to the driver as you go, but with more exotic and far-flung destinations.
Operated by several carriers and airline alliances, air passes are perfect for round-the-world travellers and those
on a gap year. They allow passengers to create their own itineraries, stopping off for a few days here,
flying on there, but going at their own pace.
However, while air passes are often cheaper than regular tickets, they may be quite restrictive. Read the fine print carefully before you commit your cash.
