The gate area was incredibly short staffed, with one representative manning 4-5 flights, which caused a 3 hr delay in boarding even though the plane was all ready to leave. Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Other flights also were delayed because of this. The flight crew was awesome and I feel bad for the only gate worker on call, but Delta needs to hire more employees.

Very frustrated with boarding gate crew. She announced the plane was small and they would be limiting us to one item to carry on. Not a problem for me as I understand the tiny planes have limited space!! Not the case here! It was a rather large plane and had plenty of room for bags! So because I don’t want to be one of “those people” who ignores the request to check a carry on I did so asking if I would be able to pick it up at the bottom of the ramp on arrival in Knoxville to which she responded “yes”! Then I watched as every other passenger held onto their 2 items and boarded!! Then when we arrived in Knoxville our 2 carry ons had been put with all the other luggage and we had to go to baggage pick up and wait for all the big checked bags to come off the carousel! So she lied!! Frustrating. Next time I won’t be so nice!

Everything was great. The big planes could still stand to have a bit more leg room. Crew was amazing!!

It was a good experience except when boarding a female flight attendant did not go out of her way to assist my teenage daughters in finding space for their carry-ons after their compartments were full.

The flight was excellent, I recommend people to fly with Delta

On time departure, smooth trip, flight attendant told through passengers the gate we would arrive at and the gate our outbound flight was departing from. Early arrival

The crew were very welcoming and helpful. I just wish economy had a bit more leg room. My knees were constantly hitting the chair in front of me.

Checking in at the airport the agent only booked the first keg of my trip and had my checked luggage going to the airport with a layover! Never was issued a boarding pass for the second leg or received sticker fir my checked bag. All was well in the end! Delta agents helped to resolve the situation!!!

Delayed due to an ill passenger after loading. Not preventable on Delta's part. Was in first class. The seats are becoming worn and detaching from their velcro attachments. Only got snacks on flight. The attendant was not the friendliest.

I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.

Boarding process was chaotic and disorganized. The plane needs updating in the interior. Things are broken, worn out, and dated

My luggage never arrived in Miami; still waiting a day later.

Iberia personnel on the ground is so rude. I would think twice in the future before booking another Iberia flight

Seats, comfort level ugh. Crew was not attentive, only to coach

All corners have been cut and it’s a cheap experience that no longer is distinguished from most other cheap airlines

The entertainment system got stuck in the ABBA music channel. The headsets were not loud enough. My pre purchased aisle seat was not honoured

it would good to have at least something to drink...

I can’t comment on food as it was necessary to buy it. No entertainment.

Everything was fantastic except the Iberia website and app… they left a lot of questions and induced much stress. But once on the plane, all was awesome.

Premium economy class is pathetic. Rubbed shoulders with passenger next to me all flight. Only about 20 passengers in that class but they ran out of one food option shortly after started serving the main meal. Flight attendant was curt and acted annoyed when asked any questions.
