Checked in ok for 3 flights at the airport check-in desk, but apparently I was not checked in to my connecting flights even though I was assured that I was and had seats on all 3 flights. Aer Lingus departure was also delayed for 1.5 hours which gave no time to collect bags to go through customs.

No complimentary drinks or snacks offered on a 2 hour flight was disappointing but everything else went well

All aspects were excellent - it helped that the flight was only 2/3 full and I had no one sitting in my row. The Pre-check (US Passport Control and Customs) in Dublin made everything so easy when we arrived in Chicago.

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

Great. Has a problem with DOB. Fixed 4 us. Led to a 5 hour earlier flight to London!

One of the best flight experiences I've have had in along time. Would fly with them again.

So, the trip from Dublin to LA did not really happen because the flight took off before we could finish the transfer.

Very nice experience. Flight had good entertainment system and good food options. Customer service was very friendly and nice as well.

Like - the crew were nice Dislike - sitting on the tarmac for long periods after boarding and landing.

I was not admitted to the flight!!! i need a refund for this.

Was not able to do a online check-in because the American Airlines system doesn't store our visa or other passport information, allowing us to have a trouble-free check-in. We were forced to have to check-in at the counter which Changes are upgrade status given that we were not able to check in much earlier.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

The new planes (American Eagle) are beautiful and especially comfortable. The flight attendants are consistently professional and courteous. And, while it may seem inconsequential, the new liquid tube of coffee creamer—in contrast to the powdered coffee creamer—makes all the difference in a cup of coffee.

I have been flying American Airlines—almost exclusively—for years. The airline is consistent with fares, timely departures/arrivals, and customer service, whether on the phone or in the air.

Cleared standby and gave up my seat. Terrible policy and boarding experience

Flight was delayed and they gave up my seat on my connection, even when I could still make the flight

Checked bag was severely damaged. Whole corner was riped off including 1 of 4 wheels gone. Insulation exposed. This made it not possible to fly with on my next-day American Airlines flight.

The WiFi would not connect enough for me to do my actual work. It permaspooled, disconnected, said it was connected, then wouldn't open an email... it was frustrating. I am not a tall person, 5'4" - and I felt cramped with little room to reach into my bag under the seat in front of me. I feel sorry for anyone taller than me having to fly. the one positive thing I will add, is the overhead bins are roomy enough to manage more bags than other carriers.

Air condition was not working for long both after boarding and also after landing ; unbearably hot and suffocating

On time flight, good communication about boarding, lines didn't form unnecessarily for boarding before their group was announced (kept aisles clear), friendly flight attendants and service
