I don't understand why passengers are frequently told that they must check their carry-on luggage due to the full flight and we board and find there are multiple empty overhead cabins with space for our carry-on. Crew should be more accurate in their assessment of the space (they have radios and I assumed they were in communication with a crew member on the plan who could tell them that the spaces were full or that there were remaining spaces). We were told in no uncertain terms that any remaining passengers yet to board had to check their carry on because no space remained on the plane, but there were multiple spaces available (including some that were completely empty) when we boarded. As someone who travels with things I must have with me, I do not appreciate this misinformation which causes me delay because I have to wait at baggage claim to get my small carry-on.

If Alaska Air is going to partner with other airlines, then it has to make the transition to the connecting flight better, especially if Alaska Air is the one that is running late. When I realized our 30 minutes of lateness due to weather was going to make getting to my connecting flight home more difficult ,I would have expected more from the crew than blank stares and "sorry". My son and I had 20 minutes to get from Gate E to the end of Gate K in the Chicago airport. My 50+ year-old body had to sprint and yell to get through the throngs and have any chance of arriving to the gate on time. In addition, the seats I had chosen when I purchased the connecting flight were changed so that my son and I placed in the last rows next to the bathrooms and were separated. There needs to be better communication between the airlines if one is going to be late. The thought of not making it home on time (we still had an 1.5 hour drive to get there) was stressful and unnecessary.

On time. Seats were comfortable. Staff was great. The plane was freezing cold! (And I prefer it to be cold, but it was freezing!) And they only offered water or juice. But overall, would fly again!

They had all the passengers running around the airport as they kept changing the gate (from B7 to C1 to B16). Then they were saying the flight would be delayed and then they immediately boarded it, almost standing passengers who'd wandered off thinking it was delayed.

Good and easy. Seats are a bit crammed and plane was small.

Be prepared for departure delays at SFO while the runways are under construction. No fault of the airlines, so be flexible. Alaska is my favorite air line but needs to pay flight attendants for all the time they're at work, not just when in the air.

Crew was great snacks could be approved upon. Healthier options

Everything was great but there were no entertainment options available.

Flight was delayed 2 hours. It was too cold inside the cabin. My seat mate had no jacket so she was shivering the entire flight. The stewardess says there’s no available blanket.

The plane had to sit on the tarmac for 45 minutes once it had landed. Not Alaska’s fault.

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

United is today and old, the planes, the staff, the business processes. Yet they expect premium prices for a less than average flight experience. I should have remembered to stay away from them and will remember to stay away from them in the future since I'm traveling a lot again. In a nutshell, they suck eggs.

The entertainment wasn’t playing in the app or online.

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Flight was delayed due to the late arrival of the catering truck, which is quite unacceptable. There was a beverage service, but no pretzel, or cookie, or nuts were served in coach.

On time take off…US cabins look tired and need of refresh!

Crew was great and did their best to make us comfortable and captain came out at the beginning to announce why the flight was delayed, weather situation up ahead, and kept us updated throughout the flight.

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

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

Packed in like sardines, very uncomfortable. Sitting the aisle my shoulder was rammed into numerous times by rushing flight attendants. Also flight was very cold.

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.

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

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

You plan your itineraries too closely together. My Albuquerque flight to Las Vegas was delayed by 45 minutes. Upon arriving in Las Vegas I missed my flight to Portland by 5 minutes, doors closed on a group of us!! Then another delay in Las Vegas from 10:11 schedule to 11:35 pm departure. Arrived in Portland @ 2:40 am. Had to take Uber to get to my sister’s house. On the other hand your crew members were friendly and professional. PLEASE IMPROVE YOUR FLIGHT PLANS AND BE RESPONSIVE TO YOUR CUSTOMERS NEEDS!!!!

I thought people that were clearly intoxicated were not allowed to board flights. But of course they let them and of course they sat directly behind us. Kicking seats being so loud you couldn’t hear yourself think. Cussing loudly telling a woman “she was going to punch her in the fucken face” for accidentally mixing her seat assignment up. These people should have been asked to get off the plane but no flight attendant cared. I don’t think I’ll be using spirit again. Better judgment needs to be used when letting people fly drunk.

Terrible legroom, seats do not recline, tray table the size of an iPhone, delayed flight, have to pay 5$ to get a cup of water onboard.

The flight was on time and nice as always for me with spirit but the cabin crew were not good. They left the lights on on a red eye for the entire flight.

It was the worst ever, i will be filing a lawsuit to get a refund. Our flight was delayed 4 hours so we would miss our connecting flight, we were not rebooked to our destination the same day, we were not offered any options to get home on the same day despite being clear that we absolutely cannot get stranded at night due to family, we were forced to book our own flights on a different airline to get home, and spririt is refusing a refund because our flight wasn't cancelled, only delayed. oh yeah, and they lost our luggage on the first part of the trip and you cannot get a hold of customer service when anything goes wrong, on hold for 30+ minutes. and their app breaks so you can't use that either.

The crew was the best and very accommodating I know you don't offer any complimentary items but water and coffee will not break the bank !!

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.

Flying Frontiier was extremely poor!! I paid for a7:15am flight on flight 1601 from PHL To Las Vegas and the delay was brutally, excruciatingly and disgustingly long (8 hrs). I arrived by Uber to PHL at 5:30 am and had to spend the entire 8 hr delay inside the airport. Even more atrocious was that the flight was delayed twice. On the phone with customer service for two hours and was not fully compensated. I feel taken advantage of with this airline. They offered a menial couched for another flight within 90 days to me and my husband who has never flown but this experience has made us almost 100% sure to not fly this airline and will suggest that others don’t either. We don’t want to book ever again, don’t want a menial voucher and I believe by standard and because the flight was delayed for 8 hours, I should be fully reimbursed for the entire round trip. There is no excuse why this should have ever occurred. After sharing my experience with others in Vegas and Philadelphia, I was told that Frontier airlines is notorious for long delayed flights, poor customer service and refusal to compensate people correctly. I’m very nervous to see what departing from Vegas to Philadelphia will bring.

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

Bad experience… crew are extremely strict with personal bags… they overcharge me coz my bag was one inch H

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
