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!

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.

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

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.

From Atlanta to Cabo I would have hoped on a plane that size I would have been able to breathe and wiggle my feet a little! The leg room in that plane is non existent and I am only 5”4’. And the air vent either wasn’t working very well or just could not blow air from the ceiling to the seat area as I was suffocating through the entire flight! And please don’t say I would have been more comfortable in first class because I cannot afford those rates and have always travelled Main Cabin without issues !

The pilots were good. Disappointing when planes don't have electrical ports

I liked the piloting of the aircraft. Very disappointed about lack of electrical ports. Also, although a short flight. there was enough time to hand out snacks to comfort + seats as was done for first class.

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

The control panel for the seat back screen did not work at all after takeoff.

Plane was so old it had cigarette butt trays in the seat

Everything was good, hard to really comfortable on a flight that long.
