Further Ryanair cancellations likely as pilots reject cash to work on days off

Airline faces fresh trouble as pilots turn down bonus offer to work on holidays and starting early

• How have you been affected by Ryanair's flight cancellations?

Ryanair customers face the threat of a fresh wave of flight cancellations as the airline's pilots prepare to reject an offer of a cash bonus if they give up days off.

The Guardian has obtained a draft letter signed by Ryanair pilots from across Europe, rejecting the offer and warning they will now "work to rule" - refusing to work beyond their basic contractual obligations. Ryanair had told pilots earlier this week that if they declined the 12,000 payment more flights might have to be scrapped.
