Thousands of families will have to pay an extra £160 or more for overseas holidays after travel giant Thomas Cook announced fuel surcharges on flights.
The surcharges range from £7.50 per person up to £40 for long-haul flights.
This means that a family of four travelling to Florida will have to pay an extra £160.
The surcharges apply to all bookings made from now on Thomas Cook Airlines' flight-only and package tours leaving the UK.
Brands affected are Thomas Cook, Airtours, Sunset, Manos and Club 18-30.
Thomas Cook blamed the increase on the rising price of oil and the subsequent increases in the cost of jet fuel, which have gone up by more than 40% in the last year.
Ian Ailles, Thomas Cook UK and Ireland mainstream chief executive, said: "We've worked hard to keep the impact of the rising fuel costs on our holidaymakers to a minimum but the fuel levy is an unavoidable result of the rising price of oil."
Last week, Willie Walsh, the chief executive of the British Airways-Iberia merged company International Airlines Group, warned of possible fuel surcharges across the industry.
Holiday companies Thomson and First Choice said they were also imposing fuel surcharges.
The companies said: "Thomson and First Choice regret the addition of this charge and endeavour to keep these supplements as low as possible."
