Yes, for the first time Austrian will provide the redlegroom already at the time of booking. Until now the exit row was only available on the Austrian Web Check-in portal as of 36 hours before departure. From now you can book a redlegroom along with your flight booking up to 1 year in advance.
The fees are regardless of the Economy booking class 25 EUR for all short haul flights, 40 EUR for all medium haul flights and 70 EUR for all long haul flights per seat and direction. What is new is the reservation of the first Economy Class row on Austrian long haul flights for 50 EUR.
Of course, these seats will be offered on Austrian Web Check-in in the short term and subject to availability.
