The times on your ticket are always local to each airport.
Yes. Every fare shows the total for everyone travelling with taxes and charges included, and it is the figure 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.
E-tickets go out by email after our team has checked the booking, usually within a couple of hours during office hours. Bookings made overnight are checked when the desk opens.
Your confirmation email arrives straight away with your order id, so you always have proof of the booking while you wait.
