Yep, the website has no bookable ORK-BCN flights in December. Yet *my* flights are still confirmed when I check them in "Manage My Booking". I even got the site to send me a reconfirmation by email. When are they going to get around to telling me?
I'm annoyed, I try to avoid the blue-and-yellow airline because of this kind of carry-on, and I would expect (slightly) better communication from Aer Lingus.
