British Airways pilots had commenced a two-day strike in continuous debate over pay and conditions.
Tens of thousands of passengers have been told not to go to airports, and BA says most have made alternative arrangements.
Both BA and the pilots’ union Balpa has indicated that they are willing to start new talks.
Nonetheless, the vast majority of BA flights taking off from the UK on Monday and Tuesday have been cancelled.
There was also a knock-on effect to flights on Sunday, because planes and pilots needed to be in position for prior and subsequent journeys.
Dozens of flights were cancelled and further unforeseen cancellations could happen on Wednesday.
In its most recent disclosure, BA stated: “We remain ready and willing to return to talks with Balpa.”
Meanwhile, Balpa’s general secretary, Brian Strutton, said: “It is time to get back to the negotiating table and put together a serious offer that will end this dispute.”
It is the first time BA pilots have walked out and the action could cost the airline up to £40m a day.
Some 4,000 pilots will strike and almost all of the 1,600 flights that were due to fly will be grounded.
