The gentleman at the gate I think his name is RIE was exceptional

We departed early and made up time in the air allowing us to arrive 30 minutes early. Capt was incredibly genuine and thanked every passenger for flying with Delta. Completely humble and professional!

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

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

On 2 different flights the wifi was horrible and there was no drink or snack service.

Great, on time departure, friendly and accommodating crew, great leg room, Smith flight

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

Crew was amazing, takeoff wonderful. The bathroom was disgusting from before takeoff the odor made the flight uncomfortable as you could smell the bathroom from the center of the plane where we were sitting. Smelled like raw sewage. My daughter was throwing up as we landed due to the smell and horrible turbulence as we approached Newark.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

United didn’t even try to hold the flight for me. They knew I had a tight connection and when I arrived at the gate less than 10 mins after final boarding the flight had already gone. The gate agent wasn’t even notified that I was on my way. She was told I wasn’t at the airport

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Very good. Because of the delays with my previous flight, I missed my connection, but I was able to book another flight through the United app easily.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.

Short flight - no food understandable. Flight was delayed for over an hour. Overall, it was good.

We boarded and buckled and then deplaned due to no pilot. Had to wait over 3 hours for a new pilot. Not weather related, just poor management.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Overall a good experience, however Wifi was not working on the flight.

Flight was 3 hours delayed. They gave our plan to two other routes. Need to knock that off.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

I had a TERRIBLE experience with the AA crew. I believe it was disability-related. It’s unlikely I will fly AA again.

Pros: "The flight crew were very nice. I needed help boarding and departing, and they were there every step of the way."
Cons: "Not very much room, no alcoholic drinks available, couldn’t connect to WiFi for inflight movie."

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

Frontier Airlines was AWFUL. I was an hour early for my flight and the lady refused to check me in. I had to purchase a whole new ticket with a different airline.

I missed a flight because of a delay. I had to buy a new ticket through Southwest.

Bag should not be so much money. This is how Frontier takes advantage of customers

Frontier is definitely a good option for people traveling light or on a budget - just remember to bring your own entertainment and your own headphones if you need them.

Never offer anything to drink ☹️ Flight delayed gate moved poor communication

It’s a cheap airline. I wish they had better seats.

Seats are cramped and very uncomfortable. You have to pay for everything and it is too expensive.

The experience was terrible. The flight boarded late, then after leaving the gate the plane had had to return to the gate for fuel. After 2 hours on the plane, the flight was canceled. The reasons given for the cancelation didn't sound truthful. and different reasons were given. My 15 year old daughter was flying alone on this flight. When they all disembarked the plane she kept asking the crew what she was supposed to do. No one even gave her the courtesy of a response. No one. It took another 4.75 hrs to be out of customs and baggage. She was re-booked the following day. That flight departed 2 hours late. After all of that, they offered a measly $100 flight voucher with an expiry date of 3 months! All in all a terrible experience. We won't be using Frontier again in the future.
