Airline reviews

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Everything was great. Great service, excellent communication, and early arrival

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

It was terrible, if they ran flights on time it would make a big difference.

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

They canceled our flight and left us stranded to figure it out

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

Charging and entertainment didn't work. The meal was horrible. They only came by with the drink cart one time for the 8 hour flight. They did come by with water a couple times.

Exceptional, I’d like to specifically recognize Robert for his outstanding customer service. He is professional, pleasant, and personable.

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.
