Crew was great flight was great baggage claim was a failure. It took over 1 hour for bags to arrive. Poor communication poor effort when I spoke to the supervisor about the delay

Much better than the.last. flight on SW on Thanksgiving day

Fine, but how to board on SW versus othrr airlines, is just lame. Goood staff though and all was solid otherwise.

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

It went well. Plane wasn't full. Will be great when assigned seating is in place

Everything was great except the food. The pretzels are really crappy.

For the first time in a long time we had a flawless experience with Southwest. Both flights were early and no mechanical errors at all. We were shocked and pleasantly surprised 😮.

It was fine. For some reason the flight was much longer than usual. It may have been explained, but I had noise cancelling earbuds on and missed a couple of announcements. The crew was fine, but there was a flight attendant who kept telling dumb jokes, occasionally one I found distasteful. This was my second time with him, but luckily it was a late flight so he didn't do as many. But I heard all of today's jokes twice, which was two times too many. Good takeout and landing.

One of the crew performed a hilarious skit to accompany the standard instructions. Passengers enjoyed it so much they applauded at the end!

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!

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.

If I pay extra for "comfort+" I expect leg room where I can stretch my legs. I was seated with an attendant's seat blocking my feet. Knee space was fine but my feet had less room than the non-"comfort+" seats. Also, don't go cheap on food when you have flights of 3+ hours. It's insulting.

They canceled our flight and left us stranded to figure it out

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

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

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

The staff was very friendly. The seats seemed quite small. Overall the flight was pleasant.

It was literally one of the worst travel experiences ever. My flight got delayed by over an hour and there was no communication of this from the gate staff. I realized it by checking the screen periodically. Once on board the flight attendants continued to serve alcohol to a man who was clearly already drunk and that was making a bunch of commotion. Never again will I fly United!

Charging and entertainment didn't work. The meal was horrible. They only came by with the drink cart one time for the 8 hour flight. They did come by with water a couple times.

Exceptional, I’d like to specifically recognize Robert for his outstanding customer service. He is professional, pleasant, and personable.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

the food choice of packaged chips and popcorn was utterly ridiculous for first class

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

While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!
