Cons: "While we arrived on time there was no air bridge ready.We had to wait for 15min to connect the air bridge.

Cons: "Ticket counter agent at SFO placed wrong tag on suitcase. This created lost luggage 4 four days. Boarding gate time posted on boarding pass from DUBto SFO as gate closing at 10:25 am when flight left at 12:30pm. We ran to gate to be told the gate won’t open for boarding until 11:40. While at DUB going to LHR none of the Aer Lingus staff told us we were to go to British Airways terminal until we got to counter. Why couldn’t there be advance notice?Aer Lingus is lame.

Cons: "The headsets provided for international movies sound quality was very poor.my daughter and I found ourselves using a single prong (airline headsets require two one for each ear)headphones from our phone to listen to movies with only one in. One flight attendant was not pleasant and wound up spilling a full cup of water on my lap, followed by another hitting me with the food cart. I am a frequent traveler so for me this shouldn't sway anyone's opinion on a minor instance."

Cons: "Professional staff"

Pros: "Everything went surprisingly smooth. Coffee was good, but had to pay for it"
Cons: "Didn't try the food"

Cons: "It was only an hour flight which needed no meal, but a cold drink (not water), free of charge, would have come in appreciated. This comes in very useful (and even necessary) when it is remembered that it was a morning flight which made passengers to leave their houses very early without having time to take breakfast before leaving home. And those who needed assistance with a wheel chair were left at the last point to the boarding of flight as early as 7:00 AM with no opportunity to look around for food."
