BA is expected to learn later today whether its latest pay offer has been accepted by cabin crew members of union Unite.
Crew members have been voting on the latest deal, which includes guaranteed rises in basic salary from 2011, as well as protection of existing contracts.
Unite put the offer to its members, in a consultative ballot which started in June.
At the time, Unite joint general secretary Tony Woodley said the union could not recommend the deal, as it did not restore travel perks removed by BA from striking staff.
"The fact that staff travel arrangements have not been restored to thousands of crew prevents this offer from BA being the breakthrough everyone seeks," he said.
"Failure by BA to restore travel in full means the possibility of a recommendation nil and makes acceptance of the offer uncertain."
But the latest deal was likely to be the company's "last and final offer", admitted Woodley.
The union had planned to ballot its members on further strike action, but agreed to postpone this until crew members had decided on BA's latest offer. Unite members have carried out 22 days of strike action this year.
If another strike takes place, BA's CEO Willie Walsh has pledged to fly 100% of long-haul flights.
