Better food than other airlines and the flight staff was very attentive and nice.

Delays resulting in missed connecting flight. Attendant failed to arrange special assistance as promised to get us on connecting flight. Robyn was the particular attendant.

Very good except for the boarding process which was more hectic than it should have been

The flight from Cincinnati to Philadelphia was satisfactory and uneventful.

All of my Aer Lingus flights were delayed. The seat I purchased with extra leg room was exactly the same as my previous seat that was free. I would appreciate my money back.

It was fine. Not worth the premium price. Overhead bins were so high I could barely reach and no crew offered to help me. Average food. Lounge in Dublin - 51st and green- absolutely appalling. Plagued with hordes of flies, dirty, meager food and beverages. Shameful.

Dear Aer Lingus Customer Care, I am writing to formally raise a complaint regarding my recent experience on Aer Lingus flight EI53 from Dublin to Seattle on 22/08/2025. Both my wife and I were seated in 15D, 15E directly under a faulty air conditioning unit. Even though the unit was switched off, cold air continued seeping through the sides and blew directly onto us for the entire duration of the flight (over 9 hours). We reported the issue to the cabin crew, but the only attempted solution was placing a piece of food-packaging sticker over the vent. Unsurprisingly, this had no effect. When we pressed further, the crew told us: “It is hard to fix it because we don’t have an engineer on board.” As a result, my wife and I remained exposed to constant cold airflow for the whole flight, and both of us became unwell afterwards, experiencing chills, sore throat and fever at the end of the flight. This has caused significant distress, disrupted our work plans. This experience highlights both a serious maintenance issue and a lack of adequate care for passengers. We therefore request: A full investigation into the defective AC system on this aircraft. An explanation of why no effective remedy (such as reseating us) was provided. Compensation for the illness and disruption caused to both myself and my wife. We ask for a full written response within 28 days. Should this matter not be satisfactorily resolved, we are prepared to escalate the complaint to the Irish Aviation Authority and Commission for Aviation Regulation and other relevant authorities. Thank you for your urgent attention to this matter. Sincerely, Temuujin Tuvshingal Myagmarsuren Ganbold

Best travel day I've had in a long time. Everything went perfectly, no delays. 10 out of 10

Not JetBlue's fault but Aer Lingus never explained how to transfer to JetBlue.

Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.
