Ryanair is offering customers whose flights it cancelled up to 80 vouchers per return as a goodwill gesture if they book a new flight.

The airline has sent the offer to customers whose travel plans were disrupted by the mass cancellation of 2,100 flights over a six-week period.

The offer of 40 per cancelled flight, which is landing in customers' inboxes from today, is in addition to any compensation that Ryanair must pay under EU flight cancellation law.

What's the offer?

The voucher knocks 40 or 40 off flights between 1 October 2017 and 20 March 2018 (excluding between 20 December and 7 January), so long as they are booked on the Ryanair website during October.

Ryanair says the voucher will be sent to all affected customers, who originally paid the full ticket price for a cancelled flight, by Friday. It is for each passenger and each flight that was cancelled, so if customers had both parts of their return journey cancelled, they would be sent an 80 voucher.

The voucher can be used for flights or add-ons, such as seat reservations or checked baggage. It can't be transferred to other passengers. Here's an example of a letter sent by Ryanair to a customer who'd had a return flight cancelled:
