Long delay before boarding. By the time I was informed of the delay I was already at the gate.

Long delay before boarding. By the time I was informed of the delay I was already at the gate.

Check your emails that you sent me. 9 emails were sent telling me that my flight is Delayed. Each one with a different time 7:10, 7:55, 9:31, 9:09, 9:29, 9:44, 10:00, 9:49, and 10:10. That was how my experience went.

Personal demeanor not good on flight returning to LAX..Great and superb on the way to Portland

Even though we checked in, checked bags, and went through security, I was told at the gate that I hadn’t checked in. I was pulled aside and had to verify my identity yet again. Otherwise, the flight was fine.

Quick boarding, efficient and pleasant crew. Wish they worked the mic better in the terminal to be understood more clearly.

The app is very bugy, did not work well. Other than that it was ok.

The flight was delayed an hour and it was not disclosed to the passengers until it was time to board. There was no in-flight WiFI available and such poor communication overall. Unfortunate that I was going to miss my connecting flight with poor communication on alternatives.

Interline connection was terrible. Boarding pass from American didn’t work even though it was valid. Gate agent not present to straighten out the mess until the next to the last boarding group was called.

Very bad that in future probably will avoid Alaska Airlines. They had changed the flight schedule without informing us. Paid for check in bags online, got an email confirmation. But during check in they couldn't find it in system, didn't even bother to apologize. Check in agent wasn't helpful, just said if we had to check in bags we had to pay there. Even though email confirmation said we already paid, didn't bother to check and just said do a dispute claim.

The people were nice. I did not make my flight and they immediately gave me the next one out.

Delta flight was on time, seats were comfortable, and crew was nice.

Bathrooms dirty sinks clogged. No one seemed to clean them. Plane very old

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Boarding is, as it always is… horrible. Gate lice. Slow moving zones. Too many people with carry ons

It was terrible, if they ran flights on time it would make a big difference.

Delta seems to be improving in many areas, except they are super bad with the food available. Bring back normal food service on long flights.

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

Delta flight was great from the check in all the way to arrival. However, I had a very bad experience. I requested a wheelchair and the wheelchair employee that went to pick me up from the plane in Boston to bring me to the baggage claims told me I have to pay him. I was under the impression that it was a free service and I usually give tips but the person forced me to pay and since I said no because I was upset with his demand when my daughter walked in to pick me up he demanded payment from my daughter who paid him thinking maybe now it is a charged service.

Horrible. Grateful to be alive but spent 13 hours at airport only to return back to my familys house and flight changed to next day. They tried to fix a part on plane, had no back up plane and after 10 hours , reattempted the flight and it STILL wasn't fixed. We got a meal voucher and rescheduled flight but there should be some other compensation for the 15 hours spent in airport

The gate was too far away for the connecting flight

Compared with other carriers business class for an overnight was not worth the extra expense.

Seats were comfortable. It’s was so cold and very uncomfortable. I paid 2000 miles for wifi service that was choppy the whole flight. Would like to be reimbursed for my miles Food was so disappointing. Three cold and terrible meals for $3000 round trip. This needs to be better.

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

Pilot Erika DeLong made us feel safe and at ease in a frankly scary time to be flying. Her warm smile and greeting and excellent command of the aircraft in foggy bumpy weather helped us all to calm our nerves and get us home safely.

Plenty of room for me and the cat in Premium Economy. Seat was comfortable. Boarding was a breeze. The lady at the special check-in desk was great, super helpful and professional.

Smooth flight. As always dinner could have been more generous. Breakfast was great.

Old and out of date plane, it seem like every time I fly with united there’s and issue. We were delayed,

We took off an hour late due to arrival airport not having enough gates. That was followed by 1:30 wait to get our bags delivered for the entire flight.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

The plane was late and then sat on the runway for almost 45 minutes before taking off.

We kept being told that the flight was full and that all overhead compartments were full and therefore had to check in our hand luggage. We were some of the last people to board and noticed that there was still sufficient space in the overhead compartments. We were obliged to check in hand luggage when there was space and so had to wait at luggage retrieval which took a while to then noticed damage to our luggage - not a great experience!

Worst seats I’ve ever had !!! The seats were very narrow and uncomfortable and misaligned with the seats in front of mine leading to bottom of the seat in front of mine pressing on my legs for 15.5 hours !

This was an overnight flight. There was no meal service in first class, just a simple snack basket was offered along with beverages. There should have been some type of continental breakfast prior to arrival in PHL. As an Executive Platinum American Airlines Advantage member, I received no name recognition from the first class flight attendant. When disembarking at PHL, the flight attendants were more interested in their cell phones than saying "thank you" to the passengers as they disembarked.

The flight was quick and to the point. The crew just did their job w/o excessive talking and everything was just perfect.

Awkward carry on process. Forced to check all carry on. No overhead space of worthiness. Left delayed, but made up the time. Crew was amicable.

Amazingly comfy flight - I had upgraded for a reasonable price and it was worth it. The food also was good.

Had to wait on pilot and crew to depart and had to wait to arrive at the gate because they only had 2 crews working. Delays, delays....Planes just keep getting smaller and tighter and they nickle and dime for everything. When will an airline actually wake up and make flying more enjoyable?

I paid for what I got which was cheap, I brought my own entertainment. I knew what to expect, so I could be prepared. If you’re flying economy, check in early like me. I have no problems with my flight, was on time, staff were friendly, and overall good experience.

terrible service, no room for a dog underfoot, a broken chair that is impossible to sit on and all this costs a lot of money

It was fast but uncomfortable seats. Had to pay a bit extra not sure why? Maybe in selection of all my 4 tix together ? Just knew I had a balance before getting boarding pass online when departing from satx ? And flight was delayed..

Seats are uncomfortable and too close together. Also, you missed my connection in Vegas on the way back and I ended up sleeping in the airport, flying back to Burbank instead of LAX and I got home 12 hours late.

Non-professional acting crew, Very uncomfortable seats…!! Very bad pricing with all the add-ons for seat choice, luggage fees, etc….soon you’ll charge extra for oxygen. The ticket price means Nothing because in the end, the actual amount i paid, i could have and will in the future continue to fly on a real airline…

With this price, I shouldn't complain on anything. I understand I have to pay for every services they provide. The plane could smell a little better. Advise them to use frebeeze to freshen up the interior a little bit.

Terrible. 1st and last flight on Spirit. Check in process was a nightmare. Despite arriving 1.6 hours before flight we had to be pulled from the ridiculously long line to “self check” our bags which took 10 min and required assistance. Seats are very uncomfortable , don’t move, no pockets, no entertainment, no wifi Basically like taking a time capsule back to the 70s. No thank you.

Arrived at 3:45am & found a long line where Spirit employees were standing at the counter but no one was working. Worried if I’d make the flight. Line started moving about 4:15 and got to check my bag at 4:30, realize my flight was at 5:25. Lines thru security were long, got to flight and walked right on. Spirit was cheapest when selected but not after $70/bag and $30/seat - extra $200.

Over 2 hour delay due to “weather” but all other flights were taking off with no issues. We felt lied to the entire time as well.

LA to Seattle was a smooth process. Seattle to LA was delayed more Than 6hrs

Purchasing tickets on their website is upsetting, they take the consumer for a ride...I wanted 2 tickets for me and my friend but we only had one carry on between the two of us. It was impossible to only pay for one - I had to pay for 2 carry ons and blew $50! Shame on their sleazy business practices! The seats in the airplane are shockingly uncomfortable! In the future I will only fly Spirit if I have no other reasonably priced choice. The flight and the crew were good. But still: Go Southwest Airlines!!!
