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

I'm a larger, athletic guy (6'2", 260lbs powerlifter) and I found the seats incredibly uncomfortable with minimal leg room, especially in a window seat. Now, I full understand that being smaller may change my view but even if I was 80lbs less, my legs would be the same size and I was sandwiched between my seat and the seat in front of me.

They did a fine job. Can't wait to use Delta in the future.

Seats in first class on the E175 recline too far back. I was in 2A, and the man in 1A fully reclined almost the entire flight. It took 6-7 inches of space away from me and made it very difficult to work on my laptop.

The helpful attitude of the staff, and being a wheelchair passenger everyone was helpful and understanding. The trip was made comfortable by the upgraded seat which was given without my request, that was a great surprise. Thank you Delta.

Mario was great. Made a night flight on a small aircraft pleasant and memorable.

Crew were exceptional. Plane was quiet and quite empty, so I had a row to sleep across.

The seat could use more support or cushion. I'm in my 50's and have back issues so the seats are a bit hard for longer flights.

The plane was in bad condition. We were taxied for mode than an hour because a light panel had feel off. The bathroom in first class had broken panels as well. Overall poor aircraft maintenance

My only real complaint was how much turbulence there was-and that probably can't be avoided. I felt really sick getting off the plane. But boarding was super easy, the flight attendants were friendly, the bathroom was clean. Everything else about the flight was perfectly fine. Thanks!

I had back trouble prior to my flight and everyone was great about helping me.

My tv was broken on the flight which is disappointing when you pay for a seat and expect a service

Always delays from Boston to Salt lake but this time was very long. Don’t understand while they board the passengers and then make them sit in the plane

Service for food to our seat was a bit slow. Snack choices were just pretzels or baked chips. My seat cushion was not attached. Other than Barbie, video choice were not very good or current.

After we landed, we were held on the plane for 30 minutes. There was no one at the gate once we landed and we forced to sit on a plan that had already over an hour delayed.

almost 4 hour delay as they over booked and had to wait for 8-10 volunteers to agree to travel next day.

Old plane. No outlets for laptop or phone. Seats worn out. Area around seat dirty.

I loved the flight and the crew. It was comfortable and smooth.

The crew was openly hostile and condescending to the customers. They spent the majority of that time in the rear talking and seemed really agitated when people asked questions. I heard five different people told that the information they requested was in the handout or safety brief.

ticketing issues caused many customers to have to go back to check in after waiting in security, then go through security line again.

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

They did get us booked on a later flight, but it made us miss our connecting flight. So, we had to stay and another state overnight with no luggage or clothes. Because they kept our luggage at airport for next flight on the next day.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

Crew is way too many times on the intercom re explaining the same thing

Amazing comfortable chairs great snacks super friendly staff pilots did excellent job. Smooth sailing all the way. Definitely be flying United more.

We waited too long to get water while the plane was on the Tarmac awaiting de-icing.

Easy peasy. Crew was great. Take-off and landing nice anc chill (good job by the pilot). Thank you UA!

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

The plane was delayed coming in and on the tarmac. I was coming from another flight so it made for a very long day. The stewardess kept trying to slam the overhead bins closed and I was worried that she had damaged my new luggage. They ran out of snacks and lccdsddd me a hummus box which was nice. It took them a very long time to pick up the garbage so I could not go to the washroom and had little time. To prepare for disbarment. The TV system was hard to control from the armrest and picture wasn’t clear. The crew did apologize several times for the lateness. It took the Denver airport an unusually long time to de-ice the plane.

Because I can’t stand very long in one place, I was allowed to reword.

delayed delayed delayed. was supposed to have a 2 hour layover and very nearly missed my connection.

Despite a bumpy flight the pilot was great. The rest of the crew on the other hand couldn’t care less if a passenger would colapse and die. Horrible service, robot like, lifeless…

Flight to Phoenix was delayed 1 hour and was not weather related. Flight Denver was delayed 2.5 hours and again was not weather related as the plane came from San Francisco.

No service due to turbulence. No entertainment on this type of aircraft. But nice old comfortable seats.

Great service, on time, professional experience. Great landing under challenging crosswind conditions at BWI. I made my connection in Charlotte despite the plane getting stuck finding a gate to park in on arrival. The only glitch -- the Airbus 320 from CLT to BWI was quite comfortable, but the larger 321 from Logan to Charlotte had minimal leg/knee room. I get that it's a high volume route but dang, couldn't even open my laptop it was so tight

I don’t think I should have to pay for extra legroom because I’m a tall person I had to get the extra legroom for comfort that shouldn’t be the case. I should be penalized by the airlines for being a tall person..

Uncomfortable plane, no entertainment and to board they had us standing in a line for over 20-30 minutes

Flight was delayed twice then cancelled. We were never notified of a new booking.

Flight was delayed 4 hours for no reason given. We were not updated. We were not given any food or drink. We were not offered any compensation.

There were 3 leg for the trip and each leg was delayed by 90 minutes or more. The boarding process takes forever with people waiting on the jetway even though most folks do not have carry-on. The whole process is poorly managed.

Not have to pay for every single item to take a flight. Seating and delays sucked.

Terrible. Seats are bad and the baggage policy is inconsistent

It was impossible to change a carry-on for a checked bag after the initial selection. The flight was delayed 14 hours "to allow for a late arriving aircraft." The seats were shockingly uncomfortable. This was only the second time I've seen seats that didn't recline in an airline. The first was in an East Bloc airline before the fall if the Iron Curtain.

Everything was good, and most importantly on time. They have been extremely tardy in some of my flights

They lost my baggage on my connection flight, it’s been 24 hours since I put my claim in and still no update on my bags.

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

The only issues had were outside of Frontier’s control or weren’t expected. It was a two hour flight they completed fast. We landed almost an hour ahead of schedule. The issues with no entertainment or food weren’t issues since there was no expectations. The issue of the loud or crying babies was outside of frontiers control.

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

Smooth process and flight. My favorite kind. Uneventful and on-time!
