Frequently asked questions

Is it cheaper to buy a plane ticket from San Diego Airport to Sion Airport last minute?
Booking your flight from San Diego Intl. Airport (SAN) to Sion Airport (SIR) at the last minute could save you a tidy sum if you luck out and find a bargain. However, airfares generally don't get cheaper as the departure date nears. If you hold out, flights could also be booked up or the best seats gone (that could mean the middle seat!). If you'd rather err on the side of caution, book well ahead of the date you want to leave. Remember that some of the most awesome deals can be found up to a year in advance. If your favorite carrier hasn't released its airfares yet, check back regularly as deals are constantly updated on Expedia.
