US domestic flights are to appear more expensive from tomorrow as airlines are forced to include all mandatory taxes, fees and charges in advertised fares.

Most fixed charges will be around £14 for a non-stop domestic flight, doubling on a one-stop flight. The new rules mean that a truer price will be shown on advertisements.

Passengers will also be allowed to cancel their reservation within 24 hours if they make their booking at least a week before departure,  without incurring a charge.

A lawsuit is pending in the US Court of Appeals for the District of Columbia as some airlines challenge the US Department of Transport over their decision.
