My flight was delayed and I got back around 3.5 hours later than expected. I had to get a new connecting flight

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.

Overall Delta was amazing from automatically booking us on the next flight once we missed our connection due to a delay to the constant communication throughout the entire process. We will continue to fly Delta going forward more and pay a little more if needed.

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.

I almost missed my connection in Chicago due to having to wait on a gate to be open I am assuming. Having to run from E terminal to C terminal and I barely made it there before they closed the door. This may not be the actual airline's fault it's crazy how there is so little time between flight especially when they are placed so far apart in the airport.

Unbelievably smooth boarding at IAH and the flight attendants were top notch.

We flew business fares. Was amazing. However, the check in didn't offer business fares preboarding which is less hectic. 8/10 due to this. Staff compared to Canadian carriers go above and beyond. Would gladly fly United again.

Improve the food offerings and cabin seating. My wife would prefer to fly another airline, even with a connection for a more comfortable trip. A 737-8 should not be scheduled for a 6 hour segment, which turned into 7.5 hours due to the origin ground delay.

OK, I don’t expect much from coach class. Everything basically is pretty lousy. But at least I expect my bloody luggage to get from A to B. Tap Airlines lost my luggage and it has been more than 24 hours in Lisbon and they still have not located my luggage. On top of that, they are incredibly unhelpful. They feel actually dismissive. This lousy customer service.

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

Food was poorly timed and not good.. Hand held snacks, really. I kept asking for water and never got any. Service was rushed for a 7-hour flight.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
