Delightful flight, ahead of time with a super crew, thanks

I wish Aer Lingus offered free wifi and had power outlets at the seats. Overall, the flight was good. Seat back entertainment had some interesting options. Food and snack options were mediocre at best. I enjoyed the canned red wine.

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.

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.

In business class overhead bins were minuscule. Had to use cabin staff to find a place for my carry-on bag. Boarding process was shambolic, as “passengers who needed assistance in boarding” absorbed an excessive amount of time and attention that Aer Lingus was apparently unprepared for.

Aer Lingus was fabulous.nhowever, Aiirfare Assist who Kayak routes me to to purchase tickets for m was awful. They messed up my reservation so bad that after about six hours on the phone with them over the week before departure, I had been choice but to show up at the airport. The Aer Lingus staff were amazing and got it sorted out but I would recommend not using Airfare Assist.

I had a great experience. I wasn’t sure what to expect but the crew helped me check my bags and made sure I got in the correct line to board. It was a bit of a walk to my gate so arrive early. I would recommend securing a flight that includes checking in your bag if you remotely think your baggage is over 10kg/22lbs. Be safe and upgrade unless you are carrying a backpack or weekend type baggage.

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

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

We were kicked off this flight by British Airways due to delays on our connecting flight also operated by British airways and were rebooked on a different carrier which delayed our arrival home by > 26 hours.

Everything about the flight check-in was smooth no line the plane is clean and bathroom

Excellent everywhere but Philly, the most rotten airport in the world.

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

I was put into business class. Wow! My flight attendant was great! The food amazing’

The gate at London Gatwick had confusing signs for the different zones and the staff seemed harried because people didn't know when it was their turn to come to the desk. Plus, with there were too many carry-on bag travelers, myself included. The charge scheme for checking bags is frustrating. If you travel light, you want the freedom to leave as soon as you deplane. When you are forced to gate-check your bag simply because the flight is fully booked, you lose whatever time you'd hoped to save because you're still stuck waiting for your bag to come off the conveyor belt.

Safe arrival. Improvement on Time efficiency Effective Communication will be great.

Not so good with their baggage handling as they damaged one of my check in luggage

A good flight back to Tampa and thankfully although we had a 90 minute delay because of thunder storms from Charlotte to bottom iof Florida, it was a prudent to avoid these for a comfortable flight as opposed to being tossed around with turbulence.

All went well on the flight, not happy of course with having to pay for a seat and in hold luggage of £50
