Not United Airlines' fault. It's ORL airport's fault.

Great flight. On time boarding. Smooth flight and on time arrival at EWR. The flight crew was marvelous and there was a great selection of movies on the entertainment system. Our bags were at the carousel before we got there. Another excellent flight from United.

United airlines has the best customer experience from booking to arrival. I always fly United airlines. The mileage program is excellent

They did the one thing that really matters - got to Chicago early.

I liked the snacks and the flight attendants were friendly.

Gate agent at Frankfurt was terrible. She denied PRE boarding even as it was printed on the boarding pass. Refused to look at the boarding pass and literally shouting for no reason. Frankfurt airport has horrible and rude staff who avoids trying to answer any question at all. Overall, horrible experience.

The Crew and the food was the worst I ever had in Business Class. First they told us there were no space for carry on. It was plenty of space over our 2 row seats, we had to ask to let us travel with it which was accepted. They were aware that we had to run for the connection due to the previous flight delay. Have us one hour waiting for more customers and not even offer a glass of water. Then started the service and they started to serve other passengers drinks in business and did not offer any drinks until they serve our pre ordered meal and I ask for something to drink. I had to wait until they finished to serve all passengers until Inget something. The crew was the worts I ever had for Business Class in my life.

Very turbulent trip made it pretty bearable, plus the lack of refreshments served and the lack of any air conditioning before takeoff which took an hour or more.

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

Not good - outbound flight was delayed and missed my connection even though I got to the gate after running through the airport - the agent would not let me on because the door was closed (flight had not left). There was no notification from United - overall experience was very disappointing. Additionally, I was downgraded from first class to coach on the alternative flight

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”.

It’s my new favourite airline! Everything was smooth and relaxed!

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.

The same as I stated prior. We incurred extra costs that should be reimbursed, given we were not communicated with about schedule changes.

UNDERPRISER IS A CRIMINAL ORGANIZATION. I WILL NEVER LET THEM MANAGE ANOTHER TRIP. THEY ESSENTIALLY WERE TRYING TO EXTORT ME FOR "Permission" FROM THEM not TO USE MY ROME TO DUBLIN FLIGHT. I did not use this flight, and despite many communications with both Aer Lingus and Underpricers, to the end, they insisted I could not do this, while Aer Lingus kept telling me there was no problem. And in fact, I had zero problems catching that second leg of the trip home from Dublin to LAX.. As if harrassment, underpricers sent me a rude and insensitve email insisting Aer Lingus would not honor the flight home to LAX from DUB. ON THE MORNING OF THE TRAVEL!!! KAYAK SHOULD NOT USE UNDERPRICER "services" They are dishonest and sadistic.

Because of problem with aer Lingus, I couldn’t check in until just before the flight and was stuck in the middle seat
