10.0 Wonderful
Pros:Staff where unbelievable nice and kind
C
3.0 Poor
Pros:The cleanliness of the plane was decent.
Cons:In flight when people were sleeping the crew were loud and interrupted causing you to wake up every time there was a food service or rubbish pick up. On an 11 hour flight this became very annoying when you were trying to get a good amount of sleep. The LCD screens on the back of the seats were the worst interaction I've ever witnessed on an airplane. The touch sensitivity was like something from the 1980s and made it very frustrating to select and navigate. On top of that the screens would spontaneously restart - my boyfriend and I witnessed the same interaction so it wasn't just one seat. Boarding at the terminal was not done efficiently in Dublin. The check in process with the kiosks was set up confusing and the crew helping did not help when clearly we needed it. There were no clear signs designating check in from baggage check. Baggage check that was self check out was not clear. When we received our boarding pass it stated that the doors would close at 1:30 for a 3pm flight - we got to the airport on time and were frantically trying to make it to our gate. After confusing baggage drop off we then had 2 rounds of security that was less than pleasant and we were ushered to a ground level terminal, or what was suppose to be a terminal. There was one food outlet that was understaffed with a huge line - we realized that our flight wasn't actually going to start boarding until 2pm so we could have taken our time. When boarding began they stated we were in final boarding and to not worry it was to stress out the people who hadn't been through security yet. There was no section boarding, it was just a free for all in which everyone waiting in yet another line. Very disorganized and inefficient. I would choose another airline for my next trip to Ireland.
A
8.0 Very Good
Pros:The flight attendants were friendly and helpful. We appreciated being able to preorder better meals. Good selection of in-air movies. Sitting anywhere for almost 7 hours is no fun but it could have been much worse.
Cons:Small seats. My tray table wouldn't stay up.
A
5.5 Fair
Pros:Good connecting flight. On time.
Cons:None
A
8.3 Very Good
Pros:I flew overnight from Toronto, Canada to Dublin and had a relatively pleasant experience. The food and drink trolleys came by quite quickly and frequently, and the food exceeded my expectations. The crew was friendly, for the most part. Boarding certainly could've been smoother... But overall, I'd fly Aer Lingus again for an overseas trip.
