great experience just at the end, we got in early and there wasn't anyone at the gate for 30 min so we had to just sit on the tarmac

It was all good, no delays which was a worry. All great

Website could be better with faster access to specific flight information and boarding pass once reservation is made. Not a fan of no seat selection on line. I had to consult gate agent each time to change seats on flights with lots of open seats. This cannot possibly be cost effective for airline. On plus side, Alaska seat legroom seemed larger than American. ns

I booked a round trip. I ordered a lunch going and a lunch for the return but got both lunches going. Could have been my error. Both lunches were good.

It was alright other than the changes in the Alaska Lounge. That and the migraine I had were disappointing. Other then that everything went well.

Seats were the least comfortable that I can remember ever having. Seat location just across from lavatory doors was not a good location to say the least. Wife has a back problem and to have a seat that is no adjustable for posture was torture for the three plus hour flight

Flight was delayed but it worked out fine. A woman was yelling and singing loudly throughout the flight. Unpleasant for everyone around

Your seats are so close I’m practically sitting in people’s laps and the micro thin mats on the chairs to reduce weight are atrocious in comfort

My flight was lovely and comfortable. Boarding was seamless and the flight smooth. The staff was so wonderful each time I’ve flown with Alaska it’s been such a pleasant experience I recommend Alaska to all I can.

Alaska Air always holds passengers on the flight for at least 20 minutes as they unload the luggage. This is unpleasant. Because of the o time luggage policy everyone has to sit on that plane for an extra 20 min. Let us off the plane and stop this nonsense. Everything else was great. Thank you.

Great job Southwest! My family doesn't fly often but we felt safe the whole time.

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

One of the best airlines for fast boarding, on time arrivals, and top notch service!

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 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.

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.

AC wasn't working then we sat on the tarmac in Austin for 40 minutes waiting for a gate.

I stopped flying southwest a long time ago. I don’t care for their boarding process, especially when I have a family to try and seat together. The early bird check in made it so much easier. As long as you do that, it’s great.

Excellent! Very attentive & helpful during a weather delay to keep people safe, com, and informed!

Issue during taxi lead to two hours of sitting in the tarmac and a lot of miscommunication and confusion from flight crew

Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.

Bus to plane was delayed for no apparent reason and our luggage was still on the belt when they shut it off. Took about 20 minutes to turn it back on to get our luggage.

I haven’t flown economy in over 20 years but it was not bad. Room by my feet for my bag and seat was roomy enough. Surprised in a good way.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

Second flight in a row where the entertainment system is broken. 5 hour long flight with no entertainment and flight attendants did not seem interested in resolving the matter. Very shocked to be treated this poorly considering I paid for a first class experience and have Diamond Medallion status.

The flight was scheduled for 2:30 PM. Early in the morning we got a text message saying the flight was delayed and rescheduled for 3:00 PM. We got to the airport with that in mind. Then we got a message during check-in at the flight was rescheduled again for 2:30 PM. We almost missed our flight. In fact, our bags Were told that they would not make it. At the end, everything worked out. But it is very stressful.

They were an hour late and they didn’t have my wheelchair for me

Food service was bare-bone. Better bot to have any at all rather than hand out premade coffees and cookies to random few passengers.

due to delay, we were downgraded in seating, so it was cramped

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.

Awful. I got stuck next to a person carrying a dog and behind someone with a dog. People need to board these dogs downstairs. The cabin is crowded enough with your pets

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.

It would have helped if I knew it would be air Canada jazz/rouge. The flight was ok but the planes are older and smaller with no entertainment. Fitting the carry one every one had was tricky and made the process longer. Overall it was ok but I actually booked a company other than air Canada and got them which was disappointing.I prefer American or overseas airlines over Canadian because the experience is usually better

Leave on time. We waited on the plane for hour hours and it was hot and smelly

It was the most un-special flight experience in my life.

Massimo, flight attendant was very authentic, attentive - wonderful. Food/wrap was just okay.

2 hour delay due to equipment failure. No updates via the app and airport screens (which continued to show a departure time in the past). AA eventually switched planes and the new plane was not catered or cleaned correctly.

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.

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

The plane was very warm and the crew turned on the lights for the entire snack service.

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

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.
