Airline reviews

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.

I had a wonderful experience flying with delta. The gentleman taking care of us on our flight was so nice, accommodating, and attentive. He always was smiling and giving pins to the kids which made me smile. The flight was quick too and without turbulence. Thank you for the great flying experience.

Delta is one of the best airlines I have flown

Made the Atlanta to Pittsburgh trip many times, with Delta no issues

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

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.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

This flight was ridiculous. I had to have a connecting flight from New York to orlando Florida??? The flight left late and because it was a short flight there was no first class amenities. I had one alcohol drink. The flight crew was fine, but it sure did not feel like first class. Delta to me dropped the ball by giving me a connecting flight. By the time we got to Raleigh we would have missed the next flight. Lucky for me the flight never came so now I was stuck waiting for a later flight that came in late also.

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

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 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.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

Re-checking our bags, the workers were not able to help us with boarding passes for the flight, told us to wait, then ignored us while they helped many other passengers. Until I got rude, they would have left us standing there, and even then they were very curt and dismissive in telling us where to get boarding passes printed. We made it to the gate just as they were starting to board passengers. It was just rude customer service.

While I received notice that AA 478 was delayed, the flight departed PHX and arrived PHL more than two hours late. The first class cabin service was mediocre; there were no pre-departure beverages offered; there were no warm mixed nuts served with cocktails; there was no personal greeting to me as an Executive Platinum member by the first class flight attendant. While the flight operated safely, its arrival at 0219 in the morning in PHL ended a very long day. I do not feel that American provided first class service.

Absolutely filthy flight and not equipped for a trans US

Turn on the heat. Flight was way too cold from Arizona to Chicago.

Poor on time performance. Flight was delayed due to a lightbulb. No updates from the pilot. Plane was dirty and hot, AC didn't work well.

Being back games on the in-flight entertainment. Also your flight attendants need a break, raise, or overall attitude adjustment.

Overall pleasant was delayed and caused transportation issue when landing

Good over all but my flight from. Miami to Barbados the airplane was very dirty like I have never seen before. It looked like that plane hasn’t been cleaned in a long time and I fly about one time a month.

Flight operated on tie. However, the in-flight entertainment was inoperative. No special recognition as an Executive Platinum member.

They attended to my needs as I couldn't walk and they provided a wheelchair for me.q

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Crowded plane but it flew on time and had friendly staff

The Air Canada agent was very helpful helping with my luggage and cat carrier when I went there instead of United.

United force you to download their App to do the check-in.

Economy seats were surprisingly comfortable, and snacks not too bad. Checked luggage arrived at destination without problems. It was annoying to wait until last to board as lowest-tier seats but understand it’s difficult to gauge when loading a full plane At least checked carryon luggage seemed to come off first. Annoying to have to use app to order food/drink when wifi availability didn’t allow time for it. Advance communication would have helped Food on menu seemed highly processed and unpalatable, overpriced and over packaged. So maybe a good thing to have missed chance to order

Flight was canceled with little warning. Flight was rebooked through Ontario, California and connecting flight was delayed by over three hours. Frontier is living up to their Greyhound of the skies reputation for sure.

Flight was OK. Seats were good no cell phone charges on the plane no TVs or entertainment.

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.

If you don’t check in 24 hours in advance, they will charge you $110 to check your bag instead of the $30. I did not get an email with this information and did not check in. In addition, my flight home was cancelled at layover and I had to spend the night in the airport, and then have another layover at another airport before making it home. Will not fly frontier again.

Terrible. Seats are bad and the baggage policy is inconsistent

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….

See my previous comment which is mostly about our flight from Phoenix to SFO

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

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!
