It would appear they are keen to get rid of the DUB route asap as well if their new pricing is anything to go by.
Just went to book a flight outbound on 22/3, return 25/3. Outbound price on Aer Arann's website is £34.99. Inbound on Aer Lingus (you are redirected to their site for the return) is £237.99 - for a 20 minute flight! The cheapest flight the next day was £111.99!
