LONDON - British Airways and the union representing its cabin crew were no closer to resolving a dispute over pay and conditions on Monday as a strike that has grounded thousands of flights entered its third - and busiest - day.
Operations at the airline were expected to be under more strain Monday than over the weekend as there are far more flights packed in to normal scheduling.
BA has warned knock-on effects from this walkout will carry on throughout this week and workers are due to strike again from Saturday for four days if the dispute is not resolved.
The Unite union and BA have both claimed victory over the walkout that has caused the airline to cancel over half its 1,950 flights normally scheduled over the period.
BA reported that nearly 98 percent of staff reported for work at Gatwick and more than half showed up at Heathrow, allowing it to reinstate a number of canceled flights.
However, Unite said that only 300 of its 2,200 cabin crew scheduled to work over the weekend turned up, and accused the airline of counting inbound crew to inflate the numbers of staff on duty.
BA stressed that it was legally obliged, as a listed company, to release accurate figures.
The acrimonious dispute with its workers is expected to be financially crippling for BA - analysts forecast the three-day walkout could cost the airline more than the $95 million that chief executive Willie Walsh is trying to save through the changes to workers' pay and conditions.
Business group London First, whose members include many of London's internationally-based businesses, warned on Monday that the capital's reputation as a center for global trade was being damaged by the strike.
There was little sign of appeasement from either side on Monday as Unite joint leader Tony Woodley told a rally of striking workers at a football ground near Heathrow to stand strong against BA's attempts to "blackmail and browbeat" them into accepting worse pay and conditions.
The airline on Friday offered a compromise on a proposed pay freeze this year, offering a 3 percent rise next year and the year after and then an inflation-linked increase in 2013/14 capped at 4 percent. The other changes include a switch to part-time work for 3,000 staff and a reduction in cabin crew sizes from 15 to 14 on long-haul flights from Heathrow.
Woodley said that BA was employing the "economics of the madhouse" by spending tens of millions on contingency plans for the walkout, including leasing planes and crew from rival airlines.
