No real issues on this flight other than the overhead bins said reserved for premium customers for a large section that was over non-first class seating

No real issues on this flight other than the overhead bins said reserved for premium customers for a large section that was over non-first class seating

The seats are so close to seats in front that you cannot lean forward and reach anything you may have placed or dropped on the floor.

It's no surprise that bigger overhead space would be nice, but they are super convenient and helpful with the baggage claim stuff.

I like the customer service. I was upgraded on flight, so enjoyed the better seat selection

Although delayed an hour, the gate attendants kept us notified and the rest of the trip went off with no issues.

Liked the attention and speed when getting wheelchair..........Was assured by phone that my needs would be taken care of and they were with my name.

First time flying with Alaska, and it went great. Thank you for a great experience flying to PDX.

We have always flown with Alaska when we can. As they have great customer service. This trip we had to transfer to Air LINGUS in Denver to go to Dublin. That’s where things went bad! Our checked luggage didn’t arrive. The process to make a claim was way more complicated than it should be. It took 5 days to recover our luggage. The whole time we couldn’t talk to a real person who could tell us anything. The whole time Alaska blamed Air lingus and vis a versa. No one seemed want to help us. That was the worst part.

Husband was new to the wheelchair accommodations this trip. What a blessing that was. All employees were helpful and customer service was excellent

We were delayed due to mechanical issues.. the gate attendant did a great job of updating us with regular and frequent announcements. Alcohol was no charge on flight to Portland, but we were charged on the return to Denver. No biggie. Just thought it was odd. Flight crew was great!

Flight was delayed again. I fly out every other weekend and lately the flight is delayed 3 out of five times 🤷🏻‍♀️

Southwest’s point to point system caused a 2 hour delay due to the crew being late from their inbound flight. Also, the WiFi and entertainment didn’t work on the plane.

Flight was fine. Only thing was flight was delayed nearly 2 hours. Flight was originally scheduled to depart at 7:50pm but didn't depart until 9:50pm. I got home around midnight. It was later than desired and I had to get up early next day to take kids to practice. I have noticed that last flight of day on West Coast for Southwest always tend to have delays.

The Southwest airline was ok. A big thank you to Kayak team (David), who worked with me on Sunday afternoon to rebook my travel from Burbank, CA, to CVG. My original flight on Sunday was delayed, so I had to cancel Sunday flight and rebook my travel to Monday. Could not have done it without help from David from Kayak team. Ante Soda GE Aerospace

Flight time kept changing and so did the gate. It was very frustrating

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

The Southwest employees (all two of them) were very nice and cheerful despite the fact the line to self-check a bag (simply drop it off) was hundreds of people long. Thank God I arrived early to the airport because I stood in this line for at least an hour. Once on the flight that had been delayed by an hour, we had no Wi-Fi and thus no entertainment. Finally, I hope the investor strong arm tactics against Southwest pay off in a short-term windfall to your C-Suite because the rest of you are screwed. I have been a faithful Southwest customer for 15 years due to everything you just got rid of. I'm flying to Idaho and Washington in October, both places I used to simply book with Southwest without a second thought now with Frontier (Washington) and United (Idaho) because they offer everything the "new" Southwest does but cheaper and at better times, destinations, etc. This really makes me sad...

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

I liked the boarding process with our loading group and numbers. I disliked that I couldn't guarantee our seats together. I didn't like that the Internet costs $8/ flight, but did love all the inflight options available through their app. I disliked no charging station at my seat for a 3+ hour flight.

Great! Although the flight was about 40 minutes delayed, the crew did a good job getting everything boarded quickly and efficiently.

The food could be much better. Also very unfortunate that most of business class seats were empty but I could not upgrade.

It was serviceable, nothing special but nothing awful on this leg.

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.

Yet another flight in which beverage and snack service was skipped. Other that that, firmly mediocre. Landed early, to gate late due to congestion at the gates. Airline's fault or airports fault: unknown.

The flights were on time which was great give. It was holiday travel season and there’d been some weather issues. The only complaint and this is every time with United is the terrible seat design. The head rest is not built for comfort and having my neck bent forward for a cross country trip reminded me while I try not to take United flights as a rule.

This was a very average flight. The seat was out of alignment so more uncomfortable than usual. The cabin felt not well maintained. But I safely got where I needed to go.

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

Poor seating comfort, seat cushion too thin, very uncomfortable. My luggage didi not make the flight due to equipment change. At least. United had it delivered the next day. I was without my toilet items for one day.

Luggage took too long go get off plane in Knoxville. Was almost 45 minutes after the flight landed.

Awful, tons of delays, I got into Chicago multiple hours late meaning I hit the very traffic I tried so desperately to avoid. Just empty apologies from American Airlines text alerts. Trash behavior from a trash airline.

The boarding was as always, the crew tried their best but not enough. The food was a disaster I had dietary restrictions that were half met because the company did not loaded the food for the flight. The entertainment screen was fine but content was not and also they removed the free messaging option from the flight and they charged 30 dollars for that crappy bandwidth. This flight is not worth the cost and the company is going down on quality.

As smooth as you can expect. Some issues with boarding because the previous plane took forever to deplane but overall, a good experience.

DFW-LHR Toilets not kept clean Too cramped. Aisles so narrow crew were constantly banging into people on the aisle seats. Even then, the carts used are reduced width. Other than that it was a decent flight on both legs

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

The flight itself was fine, but between the man in front of me putting his chair back, and the gentleman next to me who took up 50% of my seat, my back and neck are destroyed from the flight. I’m hoping for a better outcome flying back.

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

We were told there would be no food/beverage service due to turbulence. There was very little turbulence on the 2+ hour flight. I was in First Class and thought they could have done a quick service after take off as they had a quite bit of time before we would be reaching the predicted turbulent area. They could have at least passed out a quick bag of pretzels.

Very disappointed with the crew and the lack of attention given to the passengers. On a 5 hour flight they never offered a snack. One time offered a beverage and didn’t pick up the used cups until the flight was on final approach. The two flight attendants in our section mentioned that they were best friends and compared their pre flight shoes. When paying for first/business class there is a level of service that should be expected. These two spent the majority of the flight in their seats playing on their phones and laughing with each other. Very frustrating!!!

Flight was delayed by about an hour, once we arrived at LAX we had to take a shuttle to the baggage claim - it was completely disorganized. The agents at the shuttles were rude and unable to provide any information. Frontier charges extra for everything from bags to drinks - at the end it ends up being more expensive than flying the better airlines

Our flight was cancelled. They could do nothing to help us get another flight that was timely. Because the first leg was cancelled we were unable to get to our connection. We had to book on an entirely different airline for today. So we spent more money, lost a day of vacation and will never fly Frontier again, so the 'we are sorry, here is $100 credit' is a joke since we won't be flying on Frontier.

The seats were hard molded plastic covered in plastic vinyl. And the scam to charge people extra to sit together. Don’t they know we can just ask someone to trade seats. And watching the staff separate young children from parents… super classy. We had to guilt them into offering up our seats. This companies policies suck. Don’t give them your money.

Canceled original flight and wasn't clear on rebooked flight. Had to pay for bags which was more than the flight itself. Normal help, drinks etc. you have to pay for. This is Not a low cost airline.

The seats were dirty with crumbs and trash , looked it had not been cleaned up from a previous flight

Flight was cancelled and was not able to get another flight thru Frontier. Per frontier a refund was issued but I do not see a refund on my Afirm account.

We did not get to go on this flight because it got canceled 4 hours prior to scheduled time. We received an email that it got canceled and then 10 minutes later we received another email that it got delayed. It was very confusing and the only options they gave us for return flight home were 12 to 22 hours of travel time. That was not an option for us since we were traveling with kids and school started on Monday. We ended up opting for a refund and booking a flight back with Alaska. The flight ended up costing us $1500 and we had to book a hotel for the night. We will never book with frontier again.

Frontier charges 25 for the service of checking in and another 79 for a carry on. Will not take this janky air carrier again.

Frontier won’t help you at the airport without paying $25. Carry on was $75. Then you get on the plain and every beverage or snack is also a charge. Seats are hard and real packed in. I would never fly them again.

Plane could have been more on time. More leg room .
