British Airways has entered into the 20th day of strike action this year, with little sign of a final resolution to the dispute.
Today (June 7) is the third day in the current five day wakout, the last in the latest round of strikes.
Union Unite, which represents some has threatened to ballot its members on further industrial action later this year, which could mean more strikes this summer.
The 12-week protective period after the initial ballot, during which striking employees cannot be lawfully dismissed, ends in early June, prompting the union to reballot.
However, Unite cannot ballot on the same issue twice.
Tony Woodley, Unite joint general secretary, told delegates at a policy conference that Willie Walsh, BA's CEO continued "hard-mand stance" would "plunge the airline into a prolonged and totally needless summer of disruption".
Walsh is refusing to back down over the reinstatement of travel perks for BA cabin crew who went on strike.
A deal on cabin crew costs has already been agreed between both parties, with the staff travel issue acting as the final sticking point, according to Unite.
British Airways, meanwhile, had not ruled out further legal action against Unite.
