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.

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

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!

Great flight but super high price. Glad it was a business trip and not personal

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.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

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.

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.

Delta flights recently are always delayed AND at jfk tney get the gates further away (need To walk 20’ to get to them/all the way at the end of the terminal). Not sure whats happening but price doesnt match experience!

Only freetext wifi was available in flight; browsing WiFi required payment. Since the seats had no in flight entertainment, Delta should revisit this policy on this longer flight.

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

Good breakfast granola bar good crew seamless flight and baggage transfer we’ll done!

The boarding process on the departure from LA was rather slow even though I was in Group 1. For first class, I was not expecting to have to pay for Wi-fi but I did and then the wi-fi was spotty. The entree was surprisingly good and so that was a pleasant surprise. However, once I got to Houston, it was terrible. Unfortunately there was bad weather but the constant gate changes for my connecting flight was difficult to manage due to having to navigate back and forth between different terminals.

No screens or meal options. Freezing cold. Dirty seats. Left late.

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.

My flight was canceled a few hours before boarding. I was rebooked on Copa airlines and missed an important meeting .

Complimentary light meal would be appreciated. But great flight crew service on all legs

I boarded flight UA#1318 at Sacramento International Airport going back to Houston TX. The flight was scheduled at 5:10am. I was able to check in virtually using the United Airlines app. When I entered the airport, there was no one outside assisting with checked bags as it was for Delta Airlines. Immediately upon entering, there was a LONG, EXTREMELY LONG line to the kiosks to get boarding passes. I stand in line to get boarding passes then had to move to ANOTHER EXTREMELY LONG line to get my bags checked in. While standing in this line, we noticed an agent taking customers to 3 at a time to her station to check their bags in. Lucky for me, she called me back, checked my bags for me and I was on my way. I then encountered another long line at the TSA check and to avoid I ending up having to sign up for CLEAR to bypass it. So glad, I did.,...Both of my flights were great with no issues, butthe check in progress at Bush Airport was so much smoother. Check-in at SMF airport needs to be anaylzed and corrected. Do better United, I know you can....thanks

I was in first class. The outlets at my seat did not work. The plane was shabby and run down. I had prepurchsed a day subscription for internet that was not redeemable. I had to repurchase the internet for my flight and then it didn’t work anyway. Quite disappointed in what was supposed to be the launch of a great vacation.

United sent me a mileage plus number last year but that number is invalid so I can’t use it to check into flights or collect mileage. There is human to speak about the problem, only computers who keep asking me if I am using the correct email. It’s so frustrating and I cannot resolve it.

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

When I wanted to check in 3 hours prior to boarding time, the employees mentioned “a little over an hour delay” so I waited for an hour then I went to go look for food in the terminal and most people from that flight were in the same area looking for food. Finally I decided after food to check to see if it’s anytime closer and now it’s 2 mins until boarding closes?! What are you kidding me? I didn’t receive anything via sms about boarding now nor via email or on the intercom. I luckily made it through, barely, and then there’s no room for my carry on mind you I’m in the very first row so I had to place my purse in one further row back and my carry on sections down. Not sure who pays for better seats to get your stuff placed all over the plane but that was the worst experience I’ve ever had flying with anyone.

baggage clamed had to wait over a hour and half for all people on my flight it was terrible

My flight was canceled I was promised a reginf still not received.

The confirmation # CK8GNW and my name was not recognized/in Frontier system. I was able to check in on Frintier app so i went to the Frontier ticket agent, at time they told me that my name/ confirmation did not show up as a purchased ticket. I had to purchase a new ticket that cost $289.00 one way.

It was a short flight so no food or entertainment….

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.

They changed the timing , first delayed by 4 hours then went back to 40 mins late, we had to run back to airport to not miss our flight. This is ridiculous

An absolutely fraudulent experience. Extremely unprofessional. Terrible in all ways possible. Rude staff, flight attendants, and deceptive "policies."

I didn't like anything about the flight It was my first time and definitely my last time boarding a frontier flight. Their counter agents need training and they need to learn to communicate regularly and respectfully

Flight was delayed for more than 3 hours, crew at ONT airport was rude, and when we got to DFW the airplane had an issue landing, we had to be taxied to the terminal, and the luggage was hold until the next day.
