Should you buy an all-you-can-fly airline pass?
Airlines tend to offer unlimited passes during slower travel months. These packages typically cover a one-month period, range from $499 to $699, and require booking at least three days in advance. But the reality is that flying during these periods is already less expensive. For example, to recoup the cost of a recent $699 offer from JetBlue (which covered flights in the U.S., Mexico, and the Caribbean), you would have to fly round-trip from New York to Chicago four times. Not to mention that many programs don't include taxes and charge fees if you miss or cancel your flight. Unlimited passes are the best value if you're planning at least two trips-just make sure the airline flies where you want to go.
