Booking your journey from Brussels - National Airport (BRU) to Ivalo Airport at the last minute could save you a tidy sum if you hit the jackpot and find a real steal. However, tickets typically don't come down in price closer to the departure date. If you take a wait-and-see approach, flights could also be booked out or the best seats taken (because who wants the middle seat?). If you'd rather not take any chances, book well ahead of the date you want to leave. In fact, some of the best deals are available on Expedia up to 12 months in advance. If your favorite airline hasn't released tickets yet, check back regularly as deals are constantly updated on Expedia.
