A drink would be appreciated at least. Drop off by bus at Dublin Airport was miles away from terminal 1 for an old somebody to walk carrying luggage

Electronics are old. To Ireland and back had to have crew restart the movie screens multiple times. Love the 2 seats next to each other on the sides. Crew very accommodating and also frustrated with old electronics.
