British Airways is slapping a £5 surcharge on return flights from Thursday.The move came after Australian carrier Qantas Airways said it was increasing all its international fares by £5.90 a ticket.Dozens of carriers are expected to follow within days. Virgin Atlantic said it was keeping the option of a rise 'under review'. Air New Zealand said it was 'actively considering it'.Airlines are struggling to absorb the recent huge increase in oil prices. Crude oil is close to 13-year highs of just under $40 a barrel and some experts fear it could spiral to as much as $50 soon.A prolonged period of higher oil prices would cause havoc with airlines' finances and could see much steeper fare surcharges over the next few weeks.British Airways is believed to be facing a £100m increase in its £1bn-a-year fuel bill.The company raised ticket prices to cover oil prices in March last year when long-haul air tickets went up by around £20 a round trip and £5 per short-haul journey.Giovanni Bisignani, director-general of the International Air Transport Association, said airlines face an extra £4.5bn costs this year.Qantas chief executive Geoff Dixon said: 'Fuel represented about 15% of Qantas's costs last year, the second largest cost to the group after salaries and wages.'He added: 'The US dollar price of jet fuel today is almost 60% higher than it was 12 months ago and this has significantly increased the cost to our business.' Its increase comes in next Monday.The last time Qantas introduced a passenger fuel surcharge was in late 2000 after jet fuel prices shot up.MORE ABOUTAir TransportAmerican DollarBritish AirwaysEnergyFuel PricesQantas
