The British Airline Pilots Association (BALPA) has given notice to British Airways of its planned strike on September 9, 10 and 27. 

"Over several days of ACAS talks, BALPA put forward a number of packages that we believe would have resolved this dispute without a strike, and which we could have recommended to our members for acceptance prior to strike action. BA did not accept any of these packages, and it is clear following discussions with members over the last few days that BA's most recent offer will not gain the support of anywhere near a majority of its pilots," the association said in a statement.

BALPA said the gap between BA's position with their proposal is about £5 million (US$6 million).

"British Airways is an extremely profitable and successful company, and pilots have been proud to play their part in that. In 2018 the company announced profits of £2 billion. Over recent years BA pilots have made sacrifice after sacrifice to assist the company such as taking a pay cut, productivity increases, closing the final salary pension scheme, giving up annual leave days, a new rostering system, and reducing flying pay," it added.

A day of strike action will cost the flag carrier of the United Kingdom around £40 million (US$49 million). Three days will cost in the region about £120 million (US$147 million).

The pilot association said 93% voted in favor of taking industrial action against BA.

"Our proposal remains on the table should BA wish to reach an agreement prior to strike action," BALPA said in its statement.

British Airways flies to around 200 destinations worldwide.
