Ryanair passengers on all routes will be able to purchase reserved seating from January 10 following a successful six-month trial.

The pre-booking service will be charged at €10 each way and will include priority boarding.

The optional service allows passengers to pre-reserve seats in the front two rows, for a quick getaway on arrival, or in over wing rows (16&17), which provide greater legroom, and has proven to be very popular with Ryanair passengers during its summer 2011 trial.

Ryanair will continue to offer its Priority Boarding service for just €5, with priority and reserved seating passengers allowed to board the aircraft first. Those travelling with passengers under 16 years of age can reserve seats in row 2 only due to safety restrictions.

Ryanair’s Stephen McNamara said:“Ryanair is pleased to extend our popular reserved seat service on all our routes from 10th January 2012 when, for just €10, passengers on all routes will be able to pre-reserve their favourite seats in the front two rows, to ensure a prompt exit on arrival, or in over wing exits, for extra legroom.”

easyJet and Bmibaby have both launched launched allocated seating initiatives in recent months.
