I'm glad it wasn't only 75% full because I could get a good seat

We waited in the airplane for over 45 min for a southwest employee to make the flight. This cause over half the plane to miss their connecting flight in Denver. When we confronted the desk upon arrival, they told us the only flight they had was the next day leaving at 8:50 pm!!! Or they offered to get us to Burbank or LA, but after that we were on our own to get back to Santa Barbara. I paid for a flight from sba to bna bna to sba. My re entry into mom mode has been 💯 rough because of southwest mistake with my flight. And now I’m leaving to Reno tomorrow for a vballl tournament and just discovered that my leg in Vegas has me and my 3 kids on a stand by flight even though I had booked these ticket last year November!! Do better southwest!

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

Okay, not wonderful. Short flight. Wi-fi didn't work properly. Stuck waiting for a gate to open upon arrival for 20 or so minutes.

Worst experience I had on Southwest. Still better than most, but the seating was barely tolerable.

Cluster mess boarding. Can't wait for SWA reserved seating. Internet didn't seem to work on the plane.

Great experience flying Southwest. The crew was really kind and helpful, and very friendly with our toddler.

No space for our carryon and needed to check at plane before boarding !

Flight attendants were in a bad mood and we were late

Boarding was quick and simple However when I was at my seat there was a child kicking my me from behind which made me uncomfortable but besides that the flight was smooth

You could have NOT left me and my family high and dry by not completing the reservation changes because they no longer have the contract from Phoenix AZ to Moab Utah. There wasn't even a ticket agent for Contour in Phoenix to talk to. Cost my an additional $1600. to rent a vehicle to get my family to Utah. Now I'm left with trying to have someone make it right financially. I'm not optimistic..........

I’ve flown Contour on 4 different flights in the last couple weeks and every one of the flights were significantly delayed. Like over 2 hours delayed. 3 of the 4 were due to maintenance and one was weather, which is beyond their control. If this continues, I will not fly them anymore. It makes me concerned that they don’t have great maintenance practices. The planes are very old and worn out and the interiors need improvement. I do like the amount of space you have between seats for legroom. They also started charging for bags recently, which I think the did when they partnered up with American Airlines as a codeshare partner. American is also a disaster of an airline so I wish they had some agreement with Delta. I am glad they offer a major airline parternership though. That is certainly giving people more opportunities. I won’t fly Contour unless they have a direct flight to where I am going. If I have to connect then I am going to take Delta. The bus at the DFW airport to get on and off the aircraft is a pain and adds so much extra time to your travel experience. I hope this is temporary while they are building a new terminal, but I don’t know.

Short flight so no entertainment and none expected or appropriate. Everyone I dealt with was professional and helpful. A good experience.

Love it. No Frills but better than Spirit No Frills. It's like a simple luxury private plane especially if you've got five or six people on it because then you probably got your own section of the plane.

This was my first time flying with Contour and the Greenbrier Valley Airport. It both were excellent and the price couldn’t be beat!

I felt like a sardine in my seat. We all did. The plane was so small that I hit my head on the roof when I stood up from my seat. The service was good and the crew were nice.

Flight was cancelled, but they got him on an earlier delayed rescheduled one. Arrived Chicago 2 hours later than expected but long layover so it worked.

Flight was fine. I just forgot how smaller planes have more dips and seats in high winds.

It’s the only flight connecting Marion to Chicago, I do appreciate that it was available!

Information regarding the delayed flight could have been better, and the Contour airlines app needs some serious updates. But overall, the crew was great and the flight was uneventful.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

I wish there were outlets to charge my iPhone. The crew was great; we had a female pilot who was great with explaining what was happening and delays,

Another delayed flight. When the delays exceed the duration of the flight, it’s a problem.

Trip was great. A wild landing in Ottawa with the wind and rain, but the pilot did a great job. Always love flying United.👍

The internet service I paid for didn’t work at all and the flight crew was not very friendly.

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Overall it was good. The flight was bumpy at times, but the pilot made us aware every time. As a result, no snacks/drinks were made available. Seats were tight but that’s okay as I had a window seat.

Both of the first class flight attendants were rude, to everyone, not just us. The one in coach was more helpful to us than the ones in first class!

The baggage process at the gate was terrible. Stay was not friendly at all

They lost my bag on both the going and return flight of my round-trip.

Air condition was not working for long both after boarding and also after landing ; unbearably hot and suffocating

Flight was on-time, boarding was flawless and the crew was friendly.

American has been able to implement an algorithm that makes it possible for nearly every one of my evening flights to be late. Congratulations!

It was good. But the gate team made me check my carry on when there was plenty of space for my luggage on the plane. Otherwise our trip was fine.

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

Not sure the logic of the boarding in Groups. I was loaded first on the aisle. Then the guy in the middle. Then the guy by the window. Constantly holding up the other people boarding behind them with us blocking the aisle and this happened in most of the other rows

The arriving flight was a few minutes late, but the gate crew helped to deplane and board our outgoing flight quickly and efficiently. We were able to depart quickly and arrive at ORD almost at the posted time. Great job.

Flight was scheduled at 9:40pm. Got delayed to 10 am, the next day. crazy

The bag check, flight check-in, and onboard experience convinced my wife and me that we will actively go out of our way to avoid flying Frontier Airlines in the future. At bag check, we were informed that check-in could only be completed via the Frontier mobile app. Unfortunately, the app was extremely frustrating—sending us through repetitive, confusing loops that repeatedly forced us to decline add-on services with nearly every click. While most airline apps upsell, this one felt intentionally exhausting. As the process dragged on, we became genuinely concerned that my phone battery would die before check-in could be completed. We approached the bag check staff—who were standing together talking—and explained both our frustration and our predicament. They laughed. Later, my wife described the interaction as “gaslighting,” which felt accurate. We were then informed it would cost $25 per person simply to have our boarding passes printed. From that point forward, the tone of the experience was consistently hostile. The bag check employees were condescending and combative, behaving more like bullies than customer service staff. Unfortunately, that same attitude continued onboard. One flight attendant argued with me when I attempted to stow my backpack in the overhead bin. I explained that we had each paid $75 to check our bags specifically so we would not need to use carry-on space and could have adequate legroom. She demanded to see my ticket, pointed out that it said “no carry-on”—which I acknowledged—and I reiterated that this was precisely why we paid to check our bags. Her response was, “I don’t make the rules.” She then walked away, but not before asking if I “truly wanted to fly back to Chicago today?”—an unnecessary and unmistakable threat. It is also worth noting that despite booking our tickets together in the same transaction, we were not seated together. Upon our return to Chicago—where we could once again sit together—we compared onboard experiences. We both remarked on how unhappy the flight attendants appeared and how each of us was separately asked whether we would like to purchase a beverage. We declined. At no point was water mentioned as an option, leaving us with the clear impression that even water came at a cost—or that complimentary water, if available at all, was deliberately left unmentioned. Overall, the experience was shocking and deeply disappointing, but it was also a profound learning experience—one we will not forget and will not repeat. -Steve

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.

This company socks. It's fraud. They canceled our flight yesterday, and today we were late because of a really long line at the check in bag. At the rebook station, there was ton of people. The workers were all rude. I am gonna make a report to FTC.

The single worst check in experience I could imagine. I’ll never do any business with Frontier or any affiliated company

Too many extra fees, uncomfortable, little leg room. Will not recommend this airline.

Severe turbulence. Captain never came on to reassure passengers after things settled down.

I was shocked that there is no Wi-Fi, my flight was changed and delayed multiple times. In fact, I’m still not home…

It’s Frontier so they’d charge you for the air you breath if they can work out how but it was on time.

Everything costs something on this airline .... even snacks!! What a racket! We got to the airport nice and early only to wait in a line while there were no reps at the counter. Once we got to the counter to check our bags (which cost almost as much as the flight to check), we were told we were too early?!!! and had to wait an hour to check in. Then, to add insult to injury, because we didn't PAY to choose our seats, we were seated separately. I HATE THIS AIRLINE.
