Airline reviews

We booked a flight from FCO(Rome) with a stop over at DUB(Dublin) going to JFK. Boarding from Rome was kind of chaotic since the airport I guess is very small and we needed to shuttle to the airplane. The gate agent just let everyone and anyone go without using the sections so that took a lot longer than usual boarding. From drinking to JFk boarding was good and organized. Amazingly the flights was very smooth sailing and we’ve flown American big airplane to small companies before. The aircraft’s itself is on the older side, can’t complain tho because the plane ride wa smooth. For a 3 hour plane ride, nothing was complimentary. But for the longer leg of the plane complimentary snacks, meals and drinks were provided which was great. The food wasn’t bad either. I would fly with them again, great price and good service.

Comfortable trip , flight attendants professional as always. Only complaint was the food, We fly Aer Lingus frequently, this was the first time the quality of the meal was poor.

Everything went well. I made my connection which is always a concern.

I appteciate the very courteous staff. The flight was good. Something that wasn't good was that my bag was only checked as far as Dublin and I had a connecting flight to Vienna. (That was a mistake the ORD desk made.) Fortunately the desk at DUB was able to re-tag without me having to re-check in (which initially it seemed I might have to do.)

I had an awful experience at the ticketing agent stand. I had purchased three tickets, one of which I had the maiden name of a passenger on the ticket. They refused to help, assist, and actually delayed our process and had us miss an opportunity to purchase a ticket on the same flight. I was sent through multiple phone calls, none of which helped, and the person at the counter was the person who told me to both call Aer Lingus for help and was the person who said they could not fulfill my request that they were privy to from the beginning. My partner is still stuck in Scotland, racking up thousands of dollars in additional fees and tickets. I am very upset and two of my tickets went unused. I will never be using Aer Lingus ever again and I will continue to complain about them.

This was the most expensive economy flight per minute of flight time ever. But the quality was lacking. Extremely Aer Lingus rude staff at LHR said that the flight from London to Dublin (Ireland) was “NOT international.” Horrified at the colonial and imperial perspective. Seats were dirty with trash in seat pockets. Airline doesn’t clean or care about hygiene and safety.

When I booked the flight, I wasn't aware that this was a "no frills" flight. No wifi, no reclining seat, no complimentary soft drinks.

Charging for coffee on a business class fare??? And to not even mention it? Inexcusable. Boarding and disembarking was pathetic. Could not use a jetway on either end. Had to use stairs and walk across tarmac at origination and use stairs and be bussed to terminal at destination.

It was excellent! The plane left Chicago early. Arrived in Dublin early. The crew was excellent! It was a great experience.

The Nice airport was a horrible boarding experience. I have never experienced the kind of compressed mob (in the B12-B17 gate area) of people all unclear what was happening and no airport staff to assist. There was no signage and 1000’s of people waiting for any info for 2 hours.
