The seats were comfortable, the overhead bins were ample, the staff was helpful, attentive, and friendly. I enjoyed free texting. However, I much prefer Southwest no reserved seats (take any unoccupied seat) and their policy of two checked bags free, and ability to freely change flights. The Alaska airplane was nicer and newer than the Southwest one. Overall, my Alaska Airlines flying experience was a very positive one.

The seats were comfortable, the overhead bins were ample, the staff was helpful, attentive, and friendly. I enjoyed free texting. However, I much prefer Southwest no reserved seats (take any unoccupied seat) and their policy of two checked bags free, and ability to freely change flights. The Alaska airplane was nicer and newer than the Southwest one. Overall, my Alaska Airlines flying experience was a very positive one.

We boarded the flight just fine. After an hour of not moving people started asking what was going on. Finally after 1 hr and 40 minutes of being in this plane which was no longer fresh but hot due to all the bodies and the 114 degrees outside. They decided to open the door back up and asked whom ever wanted to deplane could and we would be boarding 15 minutes after. That did not happen. Was over a 3 hr delay and had to run to work it connecting flight once we landed in Seattle.

The flight was delayed by more than 2 hours which delayed all our plans.

Flying isn’t always fun but my flight was good and that’s saying alot

This is where things were a bit upsetting first the wheelchair assistance person not only was playing games at first leaving us to wonder. When I did get another person to help she took me to the gate the Alaska Airlines person Alex was rude. I didn't have a seat assigned which was not helping my travel anxiety, he honestly didn't seem to care when he step away I came to another agent named John who was very empathetic and kind. He looked in his computer and gave me a seat realizing my situation.

Friendly staff on the ground and in the air. On time performance. Comfortable seats and friendly flight attendants.

Everything was good except the flight out of Pasco was delayed so long we almost missed our connection in Seattle - had to literally run from one gate to the next!

No leg room but flight is smooth flying. Pretzels really?

The pilots were great. Service was good. Wish I had more room in the seating area because I was seated next to the only other large person. He took up a little of my seat as well. Very nice man. Wish the crew could have done a small shuffle to make it better for both of us. Still, it was a good trip both ways. Thank you

I didn’t know that food needed to be ordered ahead. Please include this in the reservation information. Overall, very good experience.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

Screen didn’t play movies, do I was pretty boated the entire flight.

It was very cold because the air conditioner was on high power, and my son got sick.

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

Delta is one of the best airlines I have flown

There was a loud squeaky sound the whole time we were flying.

It was a Red-Eye flight so was not comfortable enough to sleep, but seat was as expected. Crew was great and in-flight entertainment was excellent. Flight was smooth

Standard economy seats on Deltas 767 were better than Alaska premium seats on their 737 MAX9; more legroom, wider seats. Entertainment was great, no ipad or phone required. Could have included a meal service.

Plane was turned around due to fog half way into the flight, Delta did not properly direct passengers to stay on same flight and instead failed to properly rebook on Alaska

The boarding process was terrible especially with an indirect flight Chicago to Seattle to San Diego was terrible talking about we overbooked a flight idk if I’d take this airline ever again we got off our flight from Chicago to Seattle and we traveled for business and they told us our connecting flight was over booked and their was no seats asking people to take a delayed next flight and they don’t tell anyone coughing to wear masks seats 30A-B were terrible during the flight no one wants to sit next to people coughing all around I don’t want to be sick traveling for work or get sick anytime it’s very upsetting the staff doesn’t take this stuff serious to tell them to wear masks when they see people coughing and sneezing

I did not enjoy continuously being lied to about the amount of time we would circle Chicago before deciding to redirect to Milwaukee. Then the amount of time we would sit on the ground in Milwaukee waiting for gas, or to take off again. Or the amount of time it would then take to get to Chicago again, or sit on the runway waiting for a gate. The whole time continuously hopefully we would make our connecting flight that kept getting delayed as well. Only to scramble and miss it. Enough with the BS. Tell me the truth. "Sorry, things are backed up and your probably not going to make your flight. You should rebook on the next flight now rather than wait." You'll never hear those words from an airline. Speaking of which. If the flight has been redirected and/or is seriously delayed, how about making the WiFi free for everyone so they get to rebooking and reserving hotel rooms while still in the air. You've inconvenienced me already and now you want me to pay $20 for Internet so I can try to make other plans. Absolutely disgusting!

Excellent. Attendants served preflight drinks and were courteous and nice.

It was great! It’s been awhile since I’ve flown American but this most recent experience reminded me how much I enjoy flying American. Organized. Informative. Efficient. Friendly. Can’t ask for much more, except my luggage got dinged up a bit. But that could have been the airport.

It was the worst experience ever. Cabin temperature cold, for which they did not have any blankets upon my asking. We paid $125 extra for each passenger to get extra space sits; the sits were ridiculously small, tight, and uncomfortable! The flight attendant dropped ice on me and my sister! All in all, American Airlines deserves below zero!

The flight was delayed two hours, with no information as to why. The gate also changed several times which was aggravating. Would not fly through DFW again.

The inability to be flexible when you need to change a Basic Economy flight, when your company demands you book through a third party, causes raw feelings about the whole experience. A major airline should realize business and personal plans change all the time. I must save my company money on travel. Even if you have to charge me for the change, I get it. But being so rigid with a policy is not the best customer service.

WiFi was down so no entertainment and I could not work either. The flight was Very turbulent at the end (the last 20 min felt like an eternity) I appreciated the pilot for getting us there safely. The flight attending in first class was kind and attentive to everyone.

The gate crew did try to help, however they lacked the information as to whether the flight will operate or not. Being delayed 6 hours and in a limbo on whether the flight will operate or not is not fun. The airline having staffing issues is not encouraging at all.

From check-in staff to in-flight staff, everyone was wonderfully kind

The A321(?) model of the flight for 5+hrs has no seat back screens. Getting the american airlines wifi experience to watch movies on your own devices is not the same.

Spirit airlines is very bad airline staff doesnt know how to treat passangers they didnt allow us in the flight we reached 45 minutes ago from flight departure but they denied nd said you are late Very disappointed i never reccomend spirit airlines

They charge you for everything. Even water. They accepted my dog as a service dog in my reservation. Then they asked for a DOT form that was impossible to provide. I had to pay $175 for my service to fly with me, that would protect me from death if I ate peanuts. They did not however, serve peanuts on the plane.

Traveling on Spirit Airlines was awful. It was by far the worst airline we ever traveled on. There is no food service at all unless you paid for it. Even a cuppa coffee or a water was $5 . I’ve never been in a seat so close to the one in front of me. There was literally 10-12 inches from my face to the seat back in front of me. We actually all had to laugh at the size of the tray table. Never see a tray table so small, and I don’t even see the point of it. By booking through Spirit, but after I paid for checked luggage, water, coffee, I would’ve been better off going with our usual airline where everything was included. It actually would’ve been cheaper and way more comfortable. We joked that we were actually surprised they didn’t give us tokens just to use the bathroom. My daughter even knows she would never travel on Spirit again, and she’s not high maintenance at all. Aweful

The nickel and diming everyone was disappointing...I saw an elderly lady charged $80n for a seat because she didn't understand she had to purchase not only a ticket but a seat. I saw a father charged 3 times for carry ons for a stroller and 2 car seats. Very disappointing...I also overheard an employee tell a customer, "you either pay up or don't fly." It was an elderly man who was confused over having to purchase the seat...it is very confusing on what the ticket is for if not for a seat...

Spirit is very bare bones travel. You definitely get what you pay for. About as comfortable as riding a school bus. The tray table is a tiny little shelf that barely fits a phone, and there is not even a seat pocket to hold anything securely. They have an open bungee cord configuration, that phones fall out of. There are no drinks or snacks, unless you purchase them. Same for wifi, although it wasn’t even available for purchase on our outgoing flight. But the crew was friendly, and the plane was clean, although we did not check the onboard restroom. Basically, if you are looking for a very inexpensive flight to a nearby location, and you don’t care if wifi is available, it works. Our flight was around 90 minutes—Oakland to Las Vegas—so it was not horrible. I would never even consider flying cross country in it. That would be miserable. But for a quick trip of under two hours, it was worth the price.

Keep your expectations low and you will be pleasantly surprised

This was one of the smoothest flights in 37 years of flying, excellent pilots! Polite and caring staff. Nice clean and new plane 10/10

It was delayed 7 hours!!!!! We had to spend $550 on new flights so we didn’t miss our evening event for family. It was absolutely ridiculous. Our flight was suppose to leave at 9:30 am. Nobody was there to even help until 12:30. Worst experience ever.

Flight kept being delayed on airport board without any announcement. We were delayed almost 2 hours. Finally boarded and we had no pilots so we sat on a hot plane with screaming kids and no pilots for 40 minutes. Finally he came aboard and did paperwork for 10 minutes before we took off. No apologies or any explanations or even excuses from ANY staff in the entire process. Worst experience ever on the ground and the air I have had.

Delays delays and more delays in both LAX and San Jose. And then I said something else flight was supposed to arrive in Portland at 12:04 but didn't land until 2:30 PM which made me late for my appointment.

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.

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

The flight attendence were extremely rude and I am disabled

They wouldn’t let us on the flight even tho we were an hour early. No refund not even our bags that were prepaid

I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline

I appreciated the upgrade to free cary-on bag and seat selection at no charge

Flight was delay 9hrs and nothing was provided at airport, had to go and get a room to sleep in, paid for Uber back and fort with no offers until we landed back home a 1hr later for a $75 voucher for a future flight.
