Ryanair has launched the first of several promised winter sales, with one million seats now available online from €9.99.

Axar.az reports that fares are available to book until midnight this Sunday, October 1, and travel is from October to February 2018, the airline says.

As we publish, fares from Dublin to Paris Beauvais, Cologne, Hamburg and Liverpool are among those available at the €9.99 price.

The sale comes as Ryanair struggles to manage a "rostering failure" that this week saw a further 400,000 passengers disrupted by winter flight schedule changes.

As part of its efforts to deal with the crisis, the airline has announced plans to "slow its growth" by flying 25 fewer aircraft this winter among other changes.

It also plans to roll out a series of low-fare seat sales for winter 2017, starting with the "mega-sale" announced today.

Passengers of canceled flights have been sent €40 travel vouchers, and the airline continues to apologize for the rostering-related cancellations.

99pc of its customers are unaffected, it says.
