The movies using Southwest WiFi kept pausing and I had to restart multiple times.

First, my flight was a usual flight nothing exceptional or unexpected. Over all it was a normal, good flight! Second, your questionaire is wholly lacking in the proper options to which one can answer a question. Often on short flights, there is no food let alone entertainment so why isn't that reflected in your questionaire? A simple "not applicable" would cover that issue appropriately but no, your form arbitrarily enters an answer based on the initial assessment which normally isn't factual. Until you provide an accurate means of assessing flights, I'll no longer be completing of these unimpressive and misleading assessements. Thank you!

Easy to book and to get check in and get on and off.

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

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

Everything worked well. Crew was as entertaining as is possible on a plane flight. Southwest still has good legroom:

Crew was great - friendly and helpful with boarding - letting folks know where overhead space was available thus getting us out of the gate on time.

Pretty standard flight. We left late, but arrived early. The wifi entertainment is always nice. The free snacks and beverages are simple, but appreciated. I'm tall and the seats are an issue. I can deal with a short flight, but any longer, I have to find another airline where I know beforehand I have extra legroom.

What’s best is they have free 2 check in bags. Unlike budget airlines that knocks you off with fees just for you hand carried bags

Chairs are not reclinable. Not ear phones for sale. Seats should be assigned to avoid confrontations. Flight attendants were AMAZING.

I was with one of the last zones to board. It was kind of annoying to finally get called to board and my whole section was already on the plane. Clearly they boarded with previous zones. So by the time I got on board, there were no spaces for my luggage above my head. I had to put my luggage 4+ rows behind me, which meant that I had to wait even longer to get off the plane, since I had to wait for those rows to clear the aisle before I could retrieve my luggage and exit the plane. This also held up the plane cleaners, as they couldn't service my row until I cleared it, so they were all standing there waiting for me, while I'm standing there waiting for the other passengers to clear the aisle. Anyways, I wasn't in a rush this time, so I just waited, but I could see that being a problem in the future. Now, I could have checked my luggage, of course, but coincidentally, a friend of mine on the same flight got their luggage damaged (wheel completely knocked off) and was told by the Baggage Attendant in the airport that Delta doesn't "cover wheel damage" on luggage. This was disappointing to hear. I'm glad I didn't check mine through. If it were my luggage, I'd be highly frustrated to hear that. It makes me not want to check my luggage in the future.

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?

Typically I give delta excellent reviews. Our flight was delayed 2hrs, I was one of the fortunate ones who were able to get to my connecting flight. Also, annoying that on the connecting flight boarding personnel make me put away a small bag into my carryon. It small enough to put in back pocket seat, why hold me and the line up to just push it into my carryon.

Everything was great. Great service, excellent communication, and early arrival

Delta flight attendants poorly managed the boarding process and overhead storage. My bag was checked last minute and no claim ticket was provided. My bag is now lost. Complete incompetence by all flight crew involved.

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

Customer service at the gate in the flight was exceptional. On time. Aircraft and seat was decent. Thanks Delta. 💗

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

Great flight. On-time, comfortable, clean aircraft, and offered snacks pre-flight to plan for a potentially turbulent route. I wish there was Wi-Fi an all Delta Aircrafts but for a short flight this is not much of a problem.

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.

The flying experience was great. The flight was on time with no boarding issues during a peak travel period. The short cut baggage drop and process was not smooth and efficient at Dulles.

Fast checkin with the self serve terminal, good communication at the boarding gate.

Very friendly staff. The flight was on time. Need a bit heavy covers/blankets. It can get colder with a thin blanket.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

This was a 5 hour flight with no entertainment and with a snack being provided (pretzels and fruit bar), which are both high in carbs and sugar. Nuts would have been a better choice.

Never nice, United Express partners always do an amazing job.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward in a very uncomfortable position and it is not removable.

Good plane, crew, and flight. Boarding was a bit chaotic. Bathrooms were unacceptable. United DESPERATELY needs a new terminal at IAD.

United Airlines changed my flight 5 hours before I arrived at the airport. This messed up my entire day that I arrived in Japan.

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

Flight areas delayed 3 hours , train in the airport didn’t work

No overhead space so all carryons were checked. No internet.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

Multiple maintenance delays and the missed and rebooked connection changed gates at least 6 times including one which had us walking 20 minutes to another terminal and then back again. Seated our family of three in different middle seats throughout the plane and then there was an empty seat next to me. Very long travel day which I would have never agreed to if I knew the itinerary would be changed at 5 am, 2 hours before takeoff.

We were offered Flight Change due to overbooking. We accepted and chose an earlier flight. We went to Rebooking center to make the change but agent told us no changes permitted on our Basic ticket. AA should not have made the offer to change our flight.

Check bag location is full of rude employees who are unwilling to assist with issues after talking to AA on the phone and relaying messages. The boarding was good. While on the flight it got really hot. Asked flight attendant if there’s a way to drop the temp and make it more comfortable as we are flying from DC to Miami so flying from cold to hot weather. No changes made. Stayed hot and uncomfortable on the plane. When asked again about the AC being down the flight attendant said no the WiFi was down but not the AC. I mentioned it was still hot. No changes.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

On time (actually a little early). Was a good and short flight!

Great - quick boarding and landed early with an available gate.

On time, smooth, luggage was out fast at the end of the flight. About perfect.

Delayed each time on a round trip with no significant weather interference. Updates to flight times came after the fact. 30 min behind in boarding and board and phone still show an on time departure. Some mysterious extra 300 miles that came so surprising they had to fuel while we were already on board?

A lady asked to stop the flight after the tunnel pulled away and we began to depart a flight that was already hours late. The attendance respectfully stopped the the plane and had the tunnel return. After the tunnel returned the passenger claimed to have changed her mind . The tunnel was then put in reverse and the passenger remained on the plane .. They should have sent the sick passenger off the plane like initially replaced. They existed a couple off the plane prior to that situation.. So.. all and all.. it was a long and flight.. .

terrible cascading delays and unhelpful customer service. uncomfortable plane. crew was great, however!

I ended up paying $70+ dollars to for a carryon because the website is confusing and misleading. I now realize I did not need to pay that. I request a refund. I will pay extra to other airlines and not fly Frontier again.

With frontier you get what you pay for. The flight was two hours late. It’s a tight fit for the number of people they bring but you get to where you’re going cheap. Sometimes that’s more important than a nifty drink and cool TV..

Charges unexpected. For seat that didnt recline. Please reverse extra seat and carryon charge. Bad business that is a bait and switch.

Although we received an email from Kayak AND the airline, turns out we were not on Frontier’s manifest for the flight. We had to purchase tickets at the gate. Not sure where this transaction fell apart, but it did. We are now disputing the charges for the SLC to PDX flight originally booked through Kayak.

We had an awful experience getting our bags checked in. Frontier’s check in on the app manipulated us into buying the business package because that was the only option available for a checked bag which included two checked bags per person which we did not need. Upon arriving to the airport, we stood in line for what seemed like forever at the baggage check in and there was no one available at the counter. We were first in line and we were afraid we were going to miss our flight due to the baggage attendant being late. After realizing there were a lot of other people waiting at the baggage check in and no one available. I reached out to Frontier and could not get any customer service so I had to call the airport to page the baggage attendant to send someone to the counter to check in our bags before we were able to go through security , I finally spoke to the attendant at the counter and explained to her that we had to pay for two checked bags person a total of six bags when we only had a total of three bags between three people she said to reach out to Frontier and they would issue a refund for the three bags that we paid for and did not need. I reached out to Frontier which I was not able to reach anybody by phone so I had to go through their automated chat feature, which sent me around in circles until I finally reached a representative to assist me. I explained to them what happened and they explained that they were not able to assist me. I continued to push the issue with them as this was very frustrating and they finally put in a customer service ticket where we were issued a flight credit and we were so disappointed because after this experience, we NEVER want to fly Frontier again, and we do not want a credit that we will not use. Frontier charged us almost $500 for us to check three bags which is absolutely absurd! The customer service agents were not able to offer anything else other than a flight credit and I do not feel like my frustrations were truly heard , we will never use Frontier Airlines again ! Truly Theft by Manipulation! They should be ashamed!

I couldn’t check in because the app didn’t work. It took 3 Frontier employees at the counter to get me checked in. Flight left 3 hours after departure time

One crew member was rude about our bags. Be nice about it. We don’t fly a lot. And the fact that you have to pay for a carry on is ridiculous
