British Airways (BA) and Virgin Atlantic are both holding talks today with their respective staff unions, in a bid to avert strike action.
A meeting between Virgin Atlantic and the British Airlines Pilots' Association (Balpa) will take place today, as the airline seeks to avert the first strike in its 26-year history.
The dispute surrounds the interpretation of 120 annual rostered days off to which pilots have been entitled until now.
The latest round of peace talks between the Unite union and British Airways is also due to take place today, reports suggest, as both sides attempt to avert any further travel disruption.
The long-running dispute over cabin crew pay and conditions, which has caused 22 days of strikes so far this year, is nearing its first anniversary.
In an email to members, Unite's joint general secretary, Tony Woodley, said the union focused on finding a resolution with BA under the guidance of the Advisory, Conciliation and Arbitration Service (ACAS).
