Q&A: What's the BA dispute about?

The dispute between BA and its Unite unionised workers has been long-running and bitter

British Airways has had its "final" pay offer rejected by the Unite union.

Talks are due to resume between the two sides under the auspices of conciliation service Acas on Monday.

However, if they are unable to negotiate a deal, it would raise the prospect of a fresh wave of strikes.

The dispute between the airline and the union stretches back to before Christmas, and has resulted in 22 says of strike action since March.
