Although we ended up being stuck on the plane for 2 hours prior to take off due to high volume, weather and as the pilot put it, "possible military activity" the crew kept us informed every step of the way. There was one flight attendant in particular who was so full of energy and made the unfortunate circumstances not so bad. She entertained us and kept us in the loop the entire time as did the pilots. It made the 2 hours not feel so bad which was appreciated.

That we were delayed on the plane for two hours on a small plane but I know it was out of their control.

The flight attendants were very kind and hoped to make up for the pilot’s negligence.

Boarding was weird with a lack of overhead bins and then the pilot was inconsistent with updates to safety issues. We were delayed by an hour and twenty mins and then had to wait on the tarmac for another plane to leave the gate. Feels like I wasted two hours in limbo.

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.

I did not like that the gate changed and we were not notified by the gate operators, but we did receive a text message 20 minutes after the gate was changed.

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.

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.

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!

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.

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.

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.
