It was a perfect flight in all aspects! Both legs!

Great flight, 47 passengers on a 180 seat plane. Stewardess was pleasant and cheerful.

I liked the crew member who gave flight instructions on "in case of a problem:. The seats are so small that only a young teenager could sit in middle seat.

Great flight staff. Ease of boarding. Overall, very uneventful and easy trip.

Employees were kind and funny, as always! Flight was late but no announcements were made for people with tight connections to help them transition quickly. No service due to turbulence.

I recently flew Southwest from San Jose to Honolulu. I was very impressed with the flight crew, especially the flight attendant in charge of the front of the plane. She came through the aisle at least five times for drinks and water, and two times for snacks. I have not seen such service since I flew first class. Also, for the first time, they gave us the correct baggage claim number, and the luggage came out quickly. I can't wait for Southwest to have assigned seating! I absolutely hate the Cattle Call boarding procedure and the mad dash to get seats and overhead bins. However, the boarding was efficient.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

Delta flight was on time, seats were comfortable, and crew was nice.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

The dear was very limited in space. I could put my water bottle in seat basket. Also, there was no inflight entertainment in the delta app?

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

Wifi did not work and they only served water, coffee, or tea.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

Compared with other carriers business class for an overnight was not worth the extra expense.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

British Airways staff are very polite and willing to help.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

We almost missed our return flight. We got to the gate one minute from closing the cabin door, and the agent got us aboard the plane! We are so very grateful!!!!!

I already filled out a survey for this flight. We booked through KAYAK with airfare assist, and airfare assist did not confirm or honor our flight. Therefore, we had to go to a different place with a different travel agency. I tried very hard with airfare assist, They also promoted this on cheapair.com, but it was a bait and switch in both instances.

Flight was delayed in phoenix by 1 hour. When Kenny got to minneapolis st paul, Kenny missed his connecting flight to Duluth on Sun country air. Sun country customer service did nothing to help Kenny get home to Duluth. We will not fly with sun country ever again.

When we landed in Minneapolis from Providence, the ground crew was unable to move the jet bridge to meet our plane because the wheels were frozen. We waited patiently on the plane for about 45 minutes while they tried to solve this problem. It was mind boggling that this would not be more quickly resolved, or anticipated, in a place where sever winter weather is the norm. We stressed about meeting our connecting flight to Portland, which we assumed would be our only option for that day. Fortunately, when we finally raced from our gate to the next one, that Sun Country flight had been delayed so we didn't miss it. We decided not to take anything but direct flights from now on, no matter how much cheaper.

No line to check my bag. Reasonable overweight fee. When the connection was late due to weather, the gate agent opened the door and let me on the second flight. The plane waited for my luggage transfer. My bag arrived on time at my final destination:)

I had paid for a seat assignment at the time of reservation but when I checked in the night before it wasn’t there. Had to purchase another seat.

So unprofessional. They changed my connecting flight to a time that made it literally impossible to make the flight with no way to contact them or reject the changes. When I missed the flight as expected, there was no one to be found at their ticketing counter and the phone support put me on hold for an indefinite time. Since they didn't have another flight that day, all sun country air personell had left the airport (this was at 7pm) and my only options were to get a hotel for the night and come back the next afternoon to hopefully get rescheduled or buy a flight with another airline.

I purchased an aisle seat but was put in the middle seat surrounded by families with small sick children (3). That can happen anytime and I was prepared. The ticket agent questioned why I hadn’t paid for my luggage and had to explain that 2 pieces were included with my ticket. I hate that nickel and diming attitude. Please inform your staff better.

I know the airline has been open for 40 years and the flight crew looked just as old. The flight attendants were not friendly and rude. They should think of retiring this crew.

The crew was friendly, but I only got a drink, no food.
