Ryanair will allow passengers to take a second small carry-on bag on flights from Sunday.

The budget carrier has also cut its boarding card re-issue fee from £70 to £15 for passengers who have already checked in online.

The improvements, flagged earlier by the airline, have been introduced across the network.

The customer service initiatives follow the launch of a new Ryanair.com home page, 24 hour grace periods for minor booking errors, and the introduction of quiet flights before 8am and after 9pm.

Standard airport bag fees will be cut from £60 from January 3 and fully allocated seating will start from February 1.

A ‘My Ryanair’ passenger registration system is being added at the end of December, which it is claimed will allow faster bookings.

This will be followed by a ‘Share the Fare’ feature, allowing passengers to share fares via social media, a ‘Fare Finder’ feature, where customers can search for fares via price point, route or travel period, and the implementation of mobile boarding passes.

New business and family products are also being developed, along with a mobile app, tailored country-specific websites starting with Italy and Spain, and a mobile-responsive website.

The improvements come as Ryanair seeks to improve its customer service.

A spokesman said: “Ryanair is continually striving to improve our passenger experience and we are very excited at these significant improvements to our industry-leading customer service.

“We are actively listening and responding to our customers so that they can continue to expect low fares and on-time flights, but can now enjoy a second small carry-on bag and reduced boarding card reissue fees for those who have checked-in online, along with easier website access, 24 hour grace periods and quiet flights, with further improvements set to be rolled out over the coming months.”
