Airlines have reacted with fury and warned passengers will face higher fares after the UK's aviation regulator increased air traffic control charges.
The costs, paid by airlines, come after a UK air traffic control meltdown in August which led to long flight delays and left thousands stranded.
The fee will rise from £47 to £64 per flight until 2027, an increase of 43p per passenger to £2.08 on average.
Airlines said the increases "cannot be justified" given the recent disruption.
