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.

All flights were on time and boarding was issue free

Water service would be great. The way they board is terrible. Slow passengers first😂😂 They need to smart up a bit

It got me where I needed it to; not much more. It had no competition so that was why I chose it.

Plane didn’t even make it off the ground. We all had to get off and walk to a different terminal (lots of confusion) to get on a different plane. Landed fairly late, connections missed.

Crowded flight, but upbeat and kind crew. Pilot greeted us at door, flight attendant thanked a number of “special” passengers for their business, another addressed an eight-year old boy as “young man.” United obviously trying to up their game, but though all of that is nice and notable, flying still feels like moving along a human assembly line, being herded into one small space after another (boarding areas with too few seats, planes with limited personal space, shuttles (IAD) packed too full.

It was ok until we got to DC and I wanted to use my United Club pass and the snobbish receptionist said that they don’t take one pass. It took me everything itch of patience not to tell her off

Food choice was poor and we had to buy on board snacks.

We were offer chocolate cookies , not everyone eat chocolate. Thank you

Lost luggage again. Our second trip to Mykonos, and 2nd time no luggage.

Flight was well orchestrated, made up time despite circling a bit all good on United. Travelers can just be so into themselves that common courtesy has gone out window for some, but that’s not on United.
