Frequently asked questions

Is it cheaper to buy a plane ticket from St. Marys Airport (KSM) to BZN last minute?

However, airfares typically don't come down in price closer to the departure date. If you wait around, flights could also be booked solid or the best seats long gone. If you'd rather not hedge your bets, book well ahead of the date you want to leave. Note that some of the biggest deals can be found up to a year in advance. If your preferred carrier hasn't released its fares yet, check back regularly as deals are constantly updated on Expedia.
