Frequently asked questions

Is it cheaper to buy a plane ticket from SJC to Sion Airport last minute?
When it's time to book your flights, it pays to be prepared. While you may be able to score a last-minute deal on a San Jose Intl. Airport to Sion Airport (SIR) flight, fares usually don't get cheaper as the date of departure nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to lock in a domestic flight is between 28 – 35 days in advance. For international flights it's three to four months.
