The times on your ticket are always local to each airport.
Every fare shows the total for everyone travelling, with taxes and charges included. These are guide prices, and our team confirms the fare and the total with you before you pay. Bags and seats are extras you add only if you want them, at the airline’s own price.
Payment is always taken in pounds. If you are browsing from outside the UK, prices can show in your local currency at today’s rate.
It depends on the fare rules shown when you booked. Flexible fares can usually be moved, the cheapest fares often cannot, and the airline charges its own fee for any change plus any difference in fare.
Fares are non-refundable once booked unless the airline cancels your flight or the fare rules on your ticket allow a refund. Open your booking and send us a change request, or call us with your reference, and we price the change with the airline before you decide.
Every fare on the results page shows the bags it includes, both cabin and checked. Different fares on the same flight can include different bags, which is why we show it per fare rather than per airline.
If you need more, extra bags can be added at booking at the airline’s own price.
Our team books and tickets your flights with you by phone and gives you the booking reference, which is what the airline asks for at check-in.
