The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The WiFi and crew on the plane were good, however, the boarding experience was awful. I paid for the Choice Preferred and was boarded in group 5 so all overhead storage was full. They found room for our luggage, but further back making getting off the plane a nightmare. Also, we were in row 6 and the seats were extremely uncomfortable. Both my daughter and I had no leg room and couldn’t wait to get off the plane.

The charges were ridiculous for an hour flight and the turbulence was very scary.

Still need to work out the kinks on the new assigned seating boarding process. Otherwise, a very good flight.

WiFi did not work. Boarding with the new seating assignments took too long. The temperature in the terminal was obnoxious. +/- 80°

The seats are now more narrow. I paid for front row the seats in the front are even more narrow than before.

Only downside was the legroom and seat width, which is always a problem unless I spend more for a premium seat.

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

I appreciate the staff who allowed me to board though I arrived a little late! Regarding the assigned seating, I had booked my flight before this change and wasn't aware of the change at the time, and so I didn't select a seat at booking as I didn't realize it was relevant. Better communication about the change would have been helpful for preparing.

Flight attendants very hospitable and friendly. Pilot flew a smooth take off and landing.

Everything was great except for the boarding process. Everyone is lining up all at the same time and it’s hard to tell between the groups as they are way too large.

Women boarding passengers at the gate was absolutely rude and disrespectful of passengers. The flight attendant was absolutely delightful! Smiling and connected with the passengers. So happy. The seats are cramped and uncomfortable but I guess that’s just the way it is Communication regarding flight was excellent

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

We were delayed for about an hour from taking off due to traffic control procedures at the destination airport. But once in the air, the flight went well. The crew members were great and provided cabin service despite moderate turbulence during much of the flight.

it was a very short flight so my expectations were low.

As great a red-eye flight as red-eye flights can be.

Very old flight - time to retire it for newer airplanes

2+ hours delayed Outlet in row 12 did not work Tv monitors did not work Lights kept off the entire flight for at 5pm-7pm flight

Very disappointing given gate agent behavior. Filed a formal complaint with United.

I like that the flight attendant was very attentive and helpful. The meal menu could have more of an variety of food choices.

The flight was fine, once we got underway. It was more than hour delayed

Arrived 40 min early which was great - sat in runway for 35 min so no gain. Then waited for luggage 45 min. They need to staff accordingly knowing its one of the busiest week in Phx

My flight got rerouted due to crew rest. I was sent to Dallas customer service was not very polite. Was given a $40 room voucher for Motel 6 and $12 to eat with. It delayed me by a day. Where if I would have just stuck with my original flight Arizona was delayed to Cleveland and I could have made it home. They put me on a 9:00 flight out of Dallas to Cleveland without my knowledge or consent. When originally I was told it would be 8:45 a.m. on February 1st. I told them I could not take the 9:00 flight because I did not have anybody to pick me up from the airport at that time. I'm extremely disappointed in how I was treated. And I will not fly American Airlines again.

It would be nice to have some low carb options in the snacks.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

Trip delayed for 2 hours because of rain. We boarded and have to get down the flight and reboard again.

I love American. I’ll never fly anyone else if I can help it.

The flight was on time and arrived early. The crew were friendly and helpful.

Overall experience was great. Flights were almost on time in departing and we arrived at our destination as scheduled. No issues with amenities or flight crew. Everything went well as as expected. Will fly again with American Airlines in the future!

Booked through Kayak for $236. They canceled the flight unknown to me; retaining $100 for canceling it. Found out when I went to check in. Rebooked the same flight for $400. Incredibly disappointed. The Sun Country part was as to be expected. Crowded, no food, no arm room but got me where I wanted to go.

3 seperate extremely rude unhelpful staff. Delayed flight. Lost my bag

Sat between 2 big men. I was uncomfortable. Flight was delayed twice. About 2 hours altogether.

It was a good experience. I do wish the seats were roomier. Also, I did not like being charged for my carry on bag

Exceptional take off and landing in snow and wind…thank you to the well skilled pilots!

I liked entertainment system being downloaded on my iPad. The selections were limited but I appreciated being able to use my own screen. The flight was just fine. My only issue was both terminals being far from the main airport. Especially stoning at LAX near midnight and having to wait for a bus to take us to baggage pickup. Very inconvenient.

Just fine but comfort is always an issue since the seats are so close

The Flight was fine, the staff treated me well, the flight got delayed over 5 1/2 hours for maintenance issues....but it worked out OK,, they were very apologetic about it, and it is better to not fly if there is any issue than endanger peoples lives, so in reality that was a good thing, It did cost me extra for parking because I went beyond the time I had purchased for parking at MSP. But all in all, Good flight

I did not take this flight because the reservation made by Kayak was wrong! Kayak owes me a trip from Minneapolis to Duluth.

When I got to the airport in Seattle, they told me the flight "did not exist". Kayak reserved me a seat on a flight that did not exist. This is inexcusable. I was able to change my reservation to a flight that actually did exist, but the flight was later and then I didn't make it in time for the next leg of my trip from Minneapolis to Duluth. Kayak owes me a trip from Minneapolis to Duluth, and a big apology for messing up my reservation.

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Very well recently! Frontier is improving and less harrassing customer on luggages! Positive!

Good for a budget airline! It was easy to get on, staff was really nice. Can’t say anything about the food or entertainment because it wasn’t available, which is fine.

I am writing to express my disappointment with my recent Frontier Airlines flight. I was charged $99 at the gate because my bag was said to be too large, yet once onboard there was no available overhead bin space, and I was required to place the bag under the seat in front of me anyway. This made the charge feel unnecessary and unfair. Additionally, before the flight even took off, I was asked to move from the seat I paid for into a middle seat so another passenger and her cat could have my seat to themselves. I was not offered compensation or an explanation for being moved from a paid seat. Between the unexpected bag fee and being forced to give up my seat, this experience fell well below acceptable customer service standards. I would appreciate a review of this situation and appropriate compensation.

It was costly and difficult to check in. $85 to take a small suitcase with me, carry on or checked and $75 on the return trip, Plus $25 if I didn't check my self in check in $25, because I couldn't do it on the kiosk. Small very uncomfortable seats, waited on the runway for near an hour each way. It was my worst flight to date.

It was ok. It was expensive to check 2 bags ($75.00 per bag), and then it took a long time to wait for shuttle to take us from one terminal to the terminal where the plane was taking off at LAX. And all of this for a flight where we had to pay for any food or drink that was not water.
