Pros: "Friendly flight crew. Food was good as well with options!"
Cons: "My seat was pretty uncomfortable, not sure why but my tailbone was killing me halfway through the flight. That rarely happens to me."
Pros: "Quick boarding and departed on time."
Cons: "Everything else. Air Lingus is like Ryan Air with an Irish accent. No space, terrible food, very low quality entertainment system with the sound muffled and barely audible."
Cons: "The flight attendants were just awesome. First time flying with Aer Lingus and I must say they are my favorite airline henceforth"
Cons: "I booked a business class, round trip ticket, only to find out that one of the legs was not."
Pros: "Seats are nice and comfy"
Cons: "Flight was late. Ground crew were atrocious and lost passengers and then insisted on counting the whole plane twice (as they got it wrong the first time). The flight was delayed by 4hrs in total and then Aerlingus denied compensation was due. Appalling performance"
Pros: "Got a free seat next to me."
Cons: "Plane delayed at one airport and again for 15 agonizing minutes at Dublin as an Aer Lingus ground crew forgot to turn on a parking indicator according to the pilot. Then nearly missed connecting flight made it by running. Nobody would allow someone to move faster through lines for a connecting fligh"
Cons: "My seat was broken, so I had to move to another. Fodd options were less than expected. Overall experience was good. Would definitely fly again, but bring my own snacks."
Cons: "The seats could have been more comfortable and . The plane was over booked"
Cons: "I didn't like being taken for a bus ride and then standing outside in the open for 10 minutes before take off to Madrid and again today being brought to Terminal 1 to have to walk long distances to get to the passport control."
Cons: "Neither wi-if nor the movie system worked. Fortunately we had strong tail winds so an 8 hour flight was 6. They should have let us know while we were still in the terminal so we could purchase a book or download a movie. Beer and wine had to be purchased on an international flight. No economy plus."
