Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Flight was late - I was downgraded from first class to coach

United overall experience is great these days. Airport experience was very organized. Staff on flight were great. App and information as good as it gets.

Great smooth flight. Had a seating change, but that was an improvement. Thanks United Airways Crew.

Flight was good but there are way to many announcements for credit cards etc.

Crew seemed a bit cranky. No seatback screens. But boarding was efficient and on time and we arrived early.

See previous note about the passenger in Denver who threw my husband's bag out of the overhead bin in order to maker room for his own. And the flight attendant back up the new passenger.

Terrible. They wouldn't allow me on my flight on the 14th..

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

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”.

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.

Fast and sensible boarding was absolutely amazing. But extortionate wifi and seats that barely moved, making me unable to sleep, didn't do a lot of favors.

I liked the front row seats. A lot of leg room. The check-in window needs to be longer

My flights with Aer Lingus were very good and I will definitely fly with them. Again in future trips to Ireland and Scotland.

Too hot. Asked for an extra glass of water and was ignored. Asked to sit in empty seats that were open because it was so hot and crowded and was denied and the seats were empty the entire flight

Crew was professional and great, flight was clean. However food was pathetic. I ordered a Hindu meal assuming no meat but they served chicken. Need to be very specific- Hindu meal should be categorize as Vegetarian - no meat or egg. Or it should be specific that we are serving meat.

Late flight Delays Poor service Poor staff Worst airline ever

Ground staff and cabin crew were excellent. Flight was perfectly on time. Zero issues.

Even after a delay, getting off the ground, thanks for keeping me safe, the airline made certain that my connecting flight was rebooked to get me to my final destination. It was actually rebooked twice, and my luggage still managed to meet me. The airline gave me a credit for food and beverage to be used at the airport vendors, regretfully, the credit did not transfer to my final boarding pass. Oh, well…

Trip was smooth, good drew, average meal, almost cold coffee. Excellent landing. Did not enjoy going down the stairs, walking to the gate, walking up the stairs, going a long walk to the exchange gate, and going down the stairs again to be bussed all the way where we originally landed to take our next flight! Over all an average experience. Thank you.

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

Both flights were delayed and we missed our connection. Our second flight was delayed 3 times. I have always had great service and never any problems with my flights on Lufthansa. My last two flights were, unfortunately, awful. I fly quite often to Germany and have had better luck with United than Lufthansa.
