Boarding issues cause delay after plane had to be replaced People were double booked Then land awaited on tarmac because of no ground crew Caused me to miss my next flight

The last time we flew Delta, we were underwhelmed. Our flight was delayed several hours and there was nothing exceptional about it when it did finally leave. That was 5 years ago, and there's been a lot of changes. There I'd now in-flight entertainment, reasonably comfortable seats, and everything was on time.

Virtually no food options.

There were many delays and cancellations due to bad thunderstorms at LGA. Despite a few hours delayed (because the airport was closed due to the storm), the flight was still schedule to leave! I was very happy about that. They did issue waivers for those who could not make the later time. Once delta got the ok to fly.. The flight left the gate very fast and we arrived and exited the plane super fast too. The process was so efficient and quick, I did not feel the waiting period. The flight attendance were so happy and positive, they made he flight very enjoyable. Great job delta!

Everything ran smoothly on this flight. No delays before, pleasant staff, great entertainment selection, okay food options, working equipment (e.g., tv in the headrest worked, seatbelts worked, lavatories were operational, etc.). This flight met all my expectations

The only hiccup was the wait time on the runway before take off. Not sure if that was the airport’s fault or the airline’s fault. We must have waited 45 minutes.

Although there were a lot of passengers on this flight, the crew was able to get everyone on the plane in an efficient manner.

We were delayed about 2 and a half hours because of the weather in Denver. I was not comfortable at all in my seat because the passenger beside me had his knee and elbow all in my personal space. I asked an attendant if it was okay for me to move and she stated that it was okay, but United switched a lot of passengers flights around so there wouldn't be any empty seats. I was stuck beside the man, all hanging out of my seat, because there wasn't an open seat available. Thank goodness the flight was only 2 hours long. Overall my experience with United was terrible and I will not be flying with them anymore.

I called to change my flight to an earlier time due to flooding in PA. The lady who helped me did an equal exchange for my ticket and waved the $200 fee. I was extremely pleased and appreciative. Also, excellent movie choices and food options. I will definitely continue flying with United.

Flight crew from Geneva was nice

The pilot held the Geneva flight for 35 minutes for late arriving inbound passengers. This helped them but hurt far more passengers connecting in Washington DC. We missed our flight and waited in standby mode all evening for a Denver flight.

Agent at the gate

My seats changed so my son and I were not sitting together. The agent at the gate was wonderful and got us seated together. I had to use the restroom and the flight attendant seemed put out, and gave me a dirty look. She than ignored me and almost hit me with her cart.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
