Aer Lingus values your comfortability and has put the necessary measures if any need for special or disability assistance arises. All you have to do is send a special assistance request at the time of booking or no later than 48 hours before departure, and Aer Lingus will put in work to make that happen for you! You are advised to arrive at the airport at least two hours before the scheduled departure time of your flight so that Aer Lingus can provide you with the best possible service.
