Frequently asked questions

Is it cheaper to buy a plane ticket from Grenoble Airport to Heathrow Airport last minute?
When it's time to book your flights, it's better to be prepared. While you could pick up a last-minute deal on a Grenoble - Isere Airport (GNB) to Heathrow Airport (LHR) 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 ahead. For international flights it's three to four months.
