However, if you pay in another currency apart from £ they will recalculate the existing charges/taxes and there may be a small amount to pay or be refunded based on changes in exchange rates since the original booking was done.
Unless there has been an increase in any tax or other charge for customs, immigration, YQ, airport service fee, passenger service charge etc since the original booking was made.
