Frequently asked questions

Is it cheaper to buy a plane ticket from SIR to Langnes Airport last minute?
Being spontaneous is a fabulous way to travel, but it isn't necessarily the ideal way to score a cheap fare.

Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. You can unleash your spontaneous side when you're exploring TOS!
