Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.

The Atlanta airport had thunderstorms, which caused our flight to be delayed by multiple hours. Once we were able to board.the gate agent was rude and was trying to rush us onto the plane because the team in the plane was about to run out of hours once we were all aboard the plane they ran into an issue where the catering truck was filling up the back of the plane and they left and had to come back because they didn’t fill it up all the way, causing even more of a delay. My seat was very tight. I didn’t have a lot of legroom overall this was a miserable experience.

Flight delayed due to ground hold. Republic airways did a great job.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Our flight was delayed multiple times and then canceled at almost 1 in the morning. We are a family of 7, traveling with 5 young children. When the flight we were supposed to fly on finally arrived after waiting all day after an international flight into JFK we were informed our flight was in need of a copilot and once they located one we would take off. Then our flight was cancelled because the copilot was over his hours and they couldn't locate another. They knew before taking off from the previous location that the copilot would be unable to fly. They could have communicated the cancellation of the flight hours in advance. Once they cancelled and the pilot and copilot got off the flight, they joked about it. While there are understandably limits on flight time for pilots, they can still handle the situation in a professional manner. The late cancellation resulted in angry passengers that required police intervention in the airport. It also occurred so late and included other delta flights that after trying 15 different hotels, we were unable to secure a hotel room, they were all booked. No rental cars were available in the area either. We ended up staying in the airport with the 5 children. We made it home after 54 hours of travel with maybe 2 hours of sleep. Our luggage was lost and had to be claimed at the airport at our final destination. This was the worst trip I have ever taken and the worst airport I have ever spent time in. I met two individuals in the airport that were kind and helpful; Tonya Maingot Williams from the can we hel desk that worked to help get us rebooked and home, as well as provide us with care bags for our extended stay in the airport. The other individual was Danielle from Buffalo Wild Wings that was so very kind when we found a place to take our family we were traveling with to eat, all 11 of us and we were able to sit down together to enjoy a meal during such a stressful time.

My flight home from Knoxville, TN, included a layover in Atlanta. I boarded the aircraft in Zone 5 and although there was limited overhead space, I was able to put my 'backpack' style roller-bag above my seat. Unfortunately, due to continued bad weather, we had to deplane. There were many people who would have missed their connection, so they rebooked. When we were re-boarding, the gate agent welcomed zone 5 and then made an announcement: All roller-bags for zone 5 passengers and higher will need to be gate checked. I promptly pushed the telescoping handle in and held my bag like a backpack. I was able to bring it on board, which was a relief. Upon entering the aircraft it became apparent that there was easily 40% open overhead space. There were audible signs of angry passengers who felt duped into checking their bags when in fact there were noticeably LESS passengers on the aircraft and TONS of overhead space. I'm not sure what kinds of parameters are used to determine when to cut off roller-bags from being brought on board, but it seemed deceptive and underhanded to have so many people get stuck checking their bags when clearly there was ample room for at least one more zone.

Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

One of the best crews and best flights I’ve ever had! Really great experience

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

It was extremely hot in the cabin the entire flight, vent air was worn

The Wi-Fi did not work, so you weren't able to watch entertainment on your own device. They did not have wired headphones so you couldn't watch it on the in-seat entertainment screen either. There was plenty of time to do a drink and snag service but the flight attendants chose not to.

Great experience, boarding was fast and efficient, so much so that we arrived to Chicago very early

Comfortable seating POS to IAH. Food options were satisfactory. Good seat from IAH to ANC. Food options could be better.

The flight did not have its customary snacks during the flight. Apparently they were never loaded on the plane.

Flight was delayed 5 hours. Updates kept changing. Sears were extremely cramped. Very little leg room. Flight attendant was rushing through with drinks and hit me in the knee either the cart and didn’t apologize. They gave a 15 dollar voucher in airport which doesn’t buy. Much and it was so late that choices were limited.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

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.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.
