Peace talks between BA and the Unite union over the cabin crew strike were adjourned last night after failing to reach an agreement.
A spokeswoman for the airline said they would resume "at a later date" while Unite said they would restart on Friday.
The talks yesterday, between BA chief executive Willie Walsh and Unite's joint general secretaries Derek Simpson and Tony Woodley, lasted for six hours.
The current strike is now in the fourth of five days. Two more five day stoppages are scheduled to start on May 30 and June 5.
The dispute is over changes to working practices among cabin crew.
BA said yesterday that it planned to increase its schedule during the next planned strike after "more cabin crew than expected decided to work as normal during this week's industrial action."
The airline said it hoped to fly 70% of its long haul services, compared to 60% this week, and 55% of its short haul services, compared to 50% this week.
Services at Gatwick and London City Airports would operate normally, BA said, and that 75% of customers with bookings between May 30 and June 3 would fly.
The carrier said "many thousands more" would be booked by BA on other airlines.
Unite said the current strike was "holding strong with crew determined to end the intimidation by the company as they fight to save their jobs."
It said the stoppage had cost BA an estimated £70m so far and could cost it as much as £152m.
BA announced a pre-tax loss last week of £531m for the year ending March 31, the worst since it was privatized in1987.
