Alaska drastically changed our flight from a direct flight to a flight with connection and a long layover. So we canceled the Alaska flight and we learned a valuable lesson that we will never book through kayak again because the third party travel agent tried to withhold our money.

It was a super old plane so the first class experience was just not luxurious
I’m not sure there is anything that can be improved, even the cost was fantastic.
We were singled out, greeted and helped with check-in at the busy airport. They offered to take our bags there and gave no fuss when we said they were carry-on. With United just last week I had to put up a fight just to get onto the flight with my one authorized carry-on.
The flight was jumping between being delayed and closer to schedule about 5 times. Alaska air website showed incorrect times while google had latest info. This panic was horrible to deal with.
The plane was delayed a bit. It wasn't a huge problem though, as we were heading back home.
Flight delay was inconvenient and exhausting getting in at 1 am. However the crew and lounge was very comfortable.
I had never flown Alaska before. Years ago I flew constantly. Flying these days is not a glamorous experience. It’s not that easy to get inexpensive direct flights either. Not glamorous but reasonably priced and comfortable. I appreciated the inflight WiFi (for messaging only but that’s ok, I like to read on flights). I didn’t check the inflight entertainment, see above. I was lucky on the AUS => SFO flight—they needed volunteers to check bags at the gate. That bumped me up a level in status so they let me move to an empty exit row. The return flight I was assigned a seat in one. Very nice. As pleasant a trip as possible these days.
It would be nice if you had free internet. Text messaging is appreciated.
Plane hit turbulence diverted to Houston. We'll probably get in after 3am
I think Southwest is the number one airline that anyone can fly I have flown for the first time Frontier and what a joke and their customer service United was a very strange experience I'm only sticking to Southwest from here on out for sure
Great job Southwest! My family doesn't fly often but we felt safe the whole time.
One of the best airlines for fast boarding, on time arrivals, and top notch service!
3 hour delay. Had to change plans and was still delayed.
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
Flight delayed four separate times. I’m now one hour hours late to landing.
Long story short, it was one of the better flight experiences I've had in some time when compared with other airlines.
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.
The plane was an older model, so it wasn’t as comfortable as others. The flight attendants were not helpful during onboarding. It was a full flight so there was chaos finding space for baggage.
Awesome! On time flight, early arrival, and a complimentary upgrade!
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
Lost one piece of luggage even though I checked in 2.5 hours before the flight
Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms
My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.
No screens or meal options. Freezing cold. Dirty seats. Left late.
Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time
It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.
Boarding was again a "free for all". We were boarding group 4, and almost the entire plane was able to board before us. It's a shame that someone who follows the rules, gets the short end of the stick. Not fair.
It was perfect! I've never flown with United before, but I definitely will in the future
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
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
They didn’t offer a water, even after I asked
Frontier had yet another flight cancellation. Have never made a complete round trip with this airline without at least one leg getting cancelled. Miserable flights - dirty, uncomfortable planes that apparently always have issues since I've had multiple delays and cancellations with them.
No frills for sure. No gate announcements about flight delay, not even water to drink on the flight.
An absolutely fraudulent experience. Extremely unprofessional. Terrible in all ways possible. Rude staff, flight attendants, and deceptive "policies."
I loked walking out on the tarmac to board and no first class. I didn't like that they have no snacks or onboard wifi to bide your time.
It was a redeye flight, so every passenger just wanted to sleep, but through the entire flight, the flight crew made announcements over the loudspeaker at maximum volume every few minutes making sleep impossible. For example: it’s 2am, and the crew decides to give an extremely detailed announcement about snacks and beverages for sale. And 3am is the perfect time to wake up everyone with a lengthy announcement about how to get a coffee refill and how to take advantage of new offer from frontier for a credit card.
While booking it was not obvious that I had to pay for carryon. Realized it only during check-in. Overall, meh!
Stop changing gates at sfo. When you are elderly going back for it’s not fun.
After 5 hours of delay, they cancelled the flight. Very disappointed
My flight to LA was cancelled. I waited at the airport for 3 hrs saying it was delayed and then all of a sudden it was cancelled. Frontier only gave me a voucher and refund but could not rebook me. Flights on other airlines were too expensive last minute. I had to drive down to LA and didn’t even take my return flight home since I had to drive. One of the worst airline experiences in my life. It’s crazy how airlines can just upend people’s plans just like that.
