2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Crew was great (professional, attentive, prompt). Snacks for 4 hrs flight is deplorable.

Flight delayed. WiFi connectivity very poor if not existant. Last minute arrival forced me to run to catch my connection.

Both of my flights arrived early and check in process was smooth

Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Much better than Spirit. I was please by the easy fast check in and boarding

Check-in and in-flight staff were better than average. The seat was a fair size but too hard and not enough padding. The cushion/pillow provided is poor (thin and seems to be disposable ,it provides no effective cushioning or support). Food was OK-ish but no choice of inflight snacks and no easy place to get drinks other than water (I could ask for juice by intruding into the staff area at the back of the plane) Entertainment was very good actually. Overall better than I expected from a US-based airline (sorry!) but compared to ANA or Singapore it was so-so. (I live in Japan so they are my comparative airlines)

Punctual, smooth flight. Crew excellent and cabin very clean. Paid for WiFi but once you close out you cannot get back in even if you paid for entire flight.

Flight crew was superb. Meal was one of the meals at altitude I’ve had

Canceled my flight couple hours before takeoff. They could not find a decent re-routing and refused to pay for when i subjected alternative with Lufthansa.

Seats a little to soft on the SFO DUB flight

Well, I think we left close to on time. Crew was “eh”.

This is a bit of a rant, but I'll try to keep it civil. The flight was delayed for 2 hours with almost ZERO updates from agents. Just "there's technical issues, we don't know if or when it'll be resolved" once an hour maybe? And the gate signs, and app never updated to show the delay until it was finally resolved. So when I called Aer Lingus to see if I could rebook, I had literally the dumbest conversation with the person on the phone there where he says "It's showing your flight departed at 11:10. So it's already departed!", where I responded, "Well, it's 12:45 and I'm on the phone with you, standing in the airport, staring at the plane. So...I'm not sure what your system is saying, but we aren't in the air right now.". He said "Nothing I can do. Since it doesn't show delayed in my system, you would be charged to reschedule." Once we finally departed 2 hours late, things were going smoothly as I would expect, except in another very strange way. The stewardesses were rolling the cart down the aisle offering drinks and I asked for a water, to which they said "Sure, you can buy a bottle". I'm not sure if this is an Aer Lingus thing. Maybe something I'd expect from Ryan Air, but for a 3 hour international flight, to not have complimentary water available for customers is an absolute first, in 15 years of flying for me. I'm not upset with the plane staff at all. They were very friendly, but Aer Lingus' policies, how they handled the delay, and the unbelievable conversation with the customer service representative, leaves a lot to be desired in those areas. Also, I'm not upset about the delay. Things happen. Technical issues. But this is a place where airlines really need to clearly communicate with their customers. They also changed gates from 12N to 13N and there was no notification on any app, or announcement over the PA. End of rant. I hope they get some feedback on how to improve communication, because otherwise, they were great. And the second leg of my trip was incredibly smooth - no nickle and diming water, no communication issues. Very professional and efficient and even landed early

Flight takeoff was delayed an hour, but arrival time was not updated at the same time as departure time, so those picking me up at the other end were not alerted to the change in my arrival.

Seats are terribly cramped. I’m only 5’2” and my knees were practically in my face. No room to put a normal size bag under the seat and when the person in front of you reclined their seat your tray table was in your lap. This is the airline’s way of cramming more seats into the plane to make more money. I’ll think twice about taking Aer Lingus again since there are a few other options from Boston to the Emerald Isle.

Couldn’t check In online, message was couldn’t check in until Sunday morning though plane left Saturday night. Checked in okay at airport but caused slot if stress.

It was poor overall. They cancelled our flight and changed it without notifying us. So we incurred extra costs by having to book a hotel for our layover. They say it's Kayak/Underpricer's responsibility to reimburse us. But Kayak/Underpricer have said it's Aer Lingus' responsibility because they are the ones with our 'booking information.' I find this situation confusing and unacceptable.
