I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Very rough getting into denver. my kid threw up it was so rough.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

Excellent service despite turbulence during the flight. Flight attendants were remarkable!

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

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

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.

It was chaotic. It was overbooked so we didn't have seats until the end but they turned out to be good seats. The gate was at the end of the airport. We had to get busses to the tarmac and board. It just seemed chaotic. Flight was OK. Food was not so good. Lufthansa used to be such a great airline and now as it's with everything else: If you have money you get comforts but if you don't then you end up below deck with the rest of the cattle.

Welp - they boarded us appropriately...then had us sit on the plane for over two hours before cancelling the flight...which meant another night in Munich. I probably had it a little better than most as over 500 people had to be accommodated/re-booked etc. The next day I boarded the same flight (for which I had now been ticketed 3 straight days) and - with "only" an hour delay, managed to finally get home over 2 days later than scheduled. I haven't flown Lufthansa to Europe in years...and I won't be looking to do so again in the future. To be clear, though, the people I interacted with - flight crew, Service Center, check-in were all professional and courteous - management is clearly to blame for their lack of communication and unpreparedness for when things go wrong.

It was a short flight, everything was good with it.

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Seat very cramped, could not recline. No cheese with meal. Staff very helpful.
