Frequently asked questions

Is it cheaper to buy a plane ticket from Cardiff Airport to Southampton Airport last minute?
When it comes to booking your flights, it's better to be prepared. While you could pick up a last-minute deal on a Cardiff Airport to SOU flight, tickets 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.
