What would be infinitely better if for Kayak to not offer this flight as if it was completely different airlines rather than United and then filtering me through some creepy discount site.

Our flight gor canceled and there was no one to help us but told us to scan the qr code and fill the forms on-line. Very poor service especially we are tourists traveling to Washington DC for the 1st time.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

The flight was canceled. I couldn't get on another flight. Meal voucher wouldn't work. The whole experience was a clusterfuck.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Flight was delayed 14 hours due to DC air show and weather. Missed connection to MUC.

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

Flight attendants were great. Food mediocre. Bamboo utensils not Great especially if you have to cut something. Seating a bit crowded.

This is the best united airlines flight that I took. The crew was very friendly and the food was tasty!

Cancelled 90 min AFTER Departure! We had to deplane and wait another hour plus for the flight to be shown as cancelled for the customer service team. There were many many angry customers.

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Had a few open seats and could use it for a great rest ful journey

It was very good. Service was friendly and efficient, and food was good.

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed

We took two long flights with Lufthansa, both were delayed making us miss our connecting flights. Lufthansa took care of the first one. The second was a switch to United and figuring out how to rebook was not a pleasant experience.

Liked the flight being almost on time (airport issues created a delay). Disliked the issue printing tag bags on the kiosk and having to wait for an hour on like to drop my bags.

One bathroom wasn’t working and the other bathroom faucet wasn’t working.

Kayak was an utter disaster. They booked the tickets through a 3rd party and the 3rd party changed the dates of the flight without checking with us. They promised to change it back, but they never did, and I eventually had to dispute the credit card charge to get my money back and had to reserve through another website. NEVER use KAYAK again!

ITA changed our 9 hr direct flight without giving any reason to 4 stop overs 24 hrs flight without delays.

On both sides of my itinerary, the planes were old, the seats did not work, the seats were filthy, and the crew were unfriendly

It was bad experience . I was about to lose my flight . The airline announced the gate very late , an hour before the flight , and you need to rush to find the gate in a big airport . The flight is a long flight and the food is poor . I difintelely not taking this airplane again

At least it was a direct flight, however the boarding process was a nightmare. 2+ hours in line to check my bag. Then told it was overbooked and I have to go standby even though I bought my ticket months ago. Then sent to another line to get on standby - another long wait and finally started yelling that my flight was boarding. They sent me somewhere else. In the end I did make the flight - among the last group to board, even though I arrived 4 hours early at the airport. Worst check in process I've ever experienced in 50 years off flying.

Paid for a seat I didn’t get. Flight attendant said they would “report “ the problem. Food terrible. No service unless requested. Plane filthy. Seats falling apart. Broken footrest. Bathroom toilet held in place with tape. No gate announcements though delayed 2 hours. Is that enough?

The flight was smooth, the premier economy seats were comfortable, the flight crew were excellent. The on board food, however, was AWFUL. I suggest bringing your own food on board.

Everything was good crew, food and comfort but the entertainment was a little bad the tvs stopped working half way through travel.

The airline did a fine job with flying. However, being kept "in the dark" after a request to close all blinds for 6 of the 9 hour flight in a daylight flight was not good. I also got stuck in the lavatory with a sticky door lock. Fortunately a fellow passenger got me out!
