If you're flying after Nov 1 and are one of the many people who have had their flight time changed by several hours, you may be able to use this to your advantage and request a refund because the time changed significantly (especially if it's a later arrival or you'd need to switch planes instead of a direct flight). Otherwise, their posted policy is a $25 change fee and used within a year. Also, check if it's one year from DATE OF PURCHASE -- some airlines have this policy, but might give you an extention.
