For a cheap flight, should I book now or wait until the last minute to get a cheap sell-off?
It depends on what you’re buying. For flexible student tickets in Canada and overseas, prices are usually determined by the date of departure, not the date of booking. Remember, students finish exams and restart classes at the same time… and there’s only so many flights. Usually the earlier you book, the better. For packages to sun destinations, if you’re willing to take what’s left at the last minute, a sell-off may be the cheapest. For South East Asia, a non-changeable, non-refundable charter ticket may be the cheapest. A charter ticket is best booked early, because although sell-offs sometimes happen, you can rarely find the dates you want.
