Frequently asked questions

Is it cheaper to buy a plane ticket from BWI to Sion Airport (SIR) last minute?
Booking your flight from BWI Marshall to Sion Airport last minute could save you dollars if you strike it lucky and find an awesome deal. However, fares usually don't drop in price closer to the departure date. If you procrastinate, flights could also be booked out or the best seats gone (hello, middle seat!). If you'd rather not take any chances, book well in advance of your departure date. Note that some of the biggest deals can be found up to 12 months in advance. If your favorite airline hasn't released its fares yet, check back regularly as offers are updated on Expedia constantly.

With Sion Airport (SIR), Belp Airport (BRN) and Lausanne (QLS-Blecherette) to pick from, connecting from Baltimore to Sion is no sweat. The city's main gateway, Sion Airport (SIR), is roughly 2 kilometers southwest of the center. Besides ticket prices, consider things like transportation options from the airport and the distance to your hotel when choosing where to fly into.
