British Airways has announced a further round of increases in fuel surcharges for its long-haul flights.
British Airways says fuel costs remain "a real burden"
From 21 April, customers buying tickets in the UK will pay a £35 ($62) charge for a one-way ticket, and £70 for a return trip.
BA last raised its fuel surcharge for long-haul flights to £30 for a one-way trip in September last year.
The airline said the increase was "regrettable" but necessary because of the high price of oil.
BA's announcement came as US light crude reached a fresh record of $70.88 a barrel, hit by growing fears over Iran's nuclear standoff with the international community.
"Our fuel costs remain a real burden," said BA's commercial director Martin George.
"The price of oil has risen above $70 a barrel and experts anticipate it staying at these levels for some time."
BA said the fuel surcharge for its short-haul flights would remain at £8 for a one-way ticket, and £16 for a return trip.
