I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

I was in Comfort and we didn’t get any drinks, chips or anything! First Class got full service on the flight and Comfort got nothing. Seat was horrible and uncomfortable

Short trip, no food and therefore no expectation for much interaction with staff who were pleasant and professional. My critique is on comfort of the seats. Exit rows and comfort seats do not provide enough personal space for 3 side-by-side seats, especially when in the middle row. Some passengers are not considerate of the middle seat and there should be signs that state something to the effect of: "please consider giving middle seats use of the armrests."

The tray table was broken and the food was terrible.

THEY FAILED ME AND I NEVER GOT ON THE FLIGHT BECAUSE IT WAS SO DELAYED! I ENDED UP HAVING TO PAY OUT OF POCKET FOR A HOTEL AND STAY IN NASHVILLE TO CATCH A FLIGHT FOR THE FOLLOWING DAY. DELTA IS POOR CUSTOMER SERVICE>

Our bag was lost so that made unnecessary chaos On our trip

More up to date movies and a live TV option like ESPN, Fox News or CNN. All they had were movies and Spotify Music and some games. Also, wifi on international flights isn't free for Skymiles members like on domestic flights via T-Mobile.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

Lost luggage! No representative of the airline present at the airport. Air France contracted the service out to a 3rd party service. The service has no ability to track the missing bag or provide a time frame on its arrival.

Upon landing our breakfast were left, which means all the tray tables were were down for on landing . Isn’t there an FAA have rule about that

Crew was great. Food and entertainment was great. There was plenty of leg room sitting in a economy seat. That being said put thicker padding at the lower part of the seat. The person seated behind me was very tall and their knees were pushed into my back the entire flight. I understand having to move your legs but it was moving into my back for a 9 hour flight!

Same day canceled, we were never informed and had to pay more with worse seating on another airline.

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

Flight itself excellent, but delayed so missed connection & got to destination 2 hrs later

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

The staff was hospitable and professional. The seat had a bit of wear. The winner shade was stuck 1/4 open. I received the best of both worlds. The morning sun was able to come in and blind the screen i was trying to use while at the same time it was too low to look out and enjoy the view. Rather embarrassing for a 1st class ticket.

Even though we were delayed, we were able to make our connection

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

More water distribution throughout flight. Food quality poor and hot items delivered not hot on both attempts. Not United Standards

Never made it to Lufthansa because of Air Canadas negligence.

Boarding and flight update was fantastic as I experienced about a 10-15 delayed for both flights. The food served onboard was great; the service of the flight attendants was excellent.

Complete mess. Our reservation was mistakenly cancelled. After almost missing the connection and walking all over the Munich airport, the Service desk got involved and we were run to our flight. Not all 4 of us in Business and not seated together as originally booked. This was the worst treatment I have ever had. And I travel a lot. 1K million miler.

There is more space in this economy seat. It felt like a better layout, not so cramped.

The staff was not at pleasant as those on the first leg of our trip.

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

Crew was excellent. Sat us together after the airline changed our seats. This was the smaller plane/shorter flight so no entertainment or food.

Lufhtansa has and can do better. The food was inedible. No individual light for reading.

The flight staff was nice. The pilot was a bit erratic with the plane.

It never happened. How could you ask me to write a review of something you are not aware of never happened????

Poor service, antiquated plane with 2-3-2. B-class config upstairs. Tight and not comfortable—not what I expected for paying B-class! AND my bag didn’t make the transfer, bag will be delivered the day after it lands!

Worst airline in the world. They downgraded me from business class to economy with no compensation.

It is an airline that has the service that used to be in the old times as a standard and now is rare. Very good.

I was unable to board this flight because of visa changes that I was not alerted about and I’ve been unable to contact Kayak to obtain a refund / credit anything.

The airline was efficient and accommodating to work with though there was a delay. Appreciate the service and smooth experience!

Flight attendant kept banging her cart into my aisle seat. Hard. Couldn’t lean seat back. Should be warned of limitations when booking seat

Flight delay of 4 1/2 hours with no reason for over 3 hours. Missed our connection in Rome & had to pay for an additional flight.

The flight was delayed for several hours. After many hours of waiting, they said it was delayed until the next day. This is completely understandable, as the staff had to wait on Boeing to approve the plane. However, the staff said hotel and meal vouchers would be issued via email (they never were). An hour after leaving the airport, our flight was cancelled.

Awful. Delay, lost vacation time and travel time now more than 24h

Excellent! Great flight attendants, good food (in business class, at least), very comfortable. Touchscreen and remote wasn’t great.
