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

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.

The plane arrived 25 minutes late, and the Wi-Fi was slower than it usually is.

Forget beverage, they didn't even have water for half the passangers?

Can not wait for seating change to reduce the amount of pre boards - it’s disheartening the abuse. And then then deplaning

If your boarding Military, it should be with ore board, and with my spouse, so rude and stupid to not let us board together and before a group. All the other airlines clearly understand Military courtesy, this is why I Rarely fly SWA and Always fly Alaska

I boarded last because of my boarding assignment and was given a middle seat at the back of the plane. I’m 6”1” so it was really tight. I wish I just had a seat assignment instead of a general boarding group. My bag was way at the front and my seat at the back. Was never offered a beverage and had no room to move.

Flight was ok. Boarding wasn’t fun. Flights were delayed by 12 minutes on each leg.

Crew was great. Helpful, friendly, sense of humor. 👍🏽 Seat was really uncomfortable -- too concave ( why make them like that???) but worst, This is the first flight I've ever been on in my life where the seat did not have the option to recline!!! Whaaaat??? I was so sleepy but never was able to get comfortable enough to actually sleep. I forget which model of a plane it was exactly, but it was a 737 of some type.

You need another option on certain questions - ones that not applicable.

We had tried to change our seats in the app multiple times before check-in but the flight was seemingly full. When we boarded, there were several empty seats available that my husband and I were offered to take by one crew member only to be told by two others that those rows were reserved for the crew members’ bags.

One of the flight attendant was very rude and not helpful. The others were good. Also seats were dirty with food bags left on the seats. Looks like the plane wasn’t clean before we boarded.

Couldn’t plug in the computer to the electrical plug underneath the seat. Should accommodate a computer power line.

I don't know what it is. But it seems that flights from Ontario to Seattle are always delayed. This one was delayed 3 hours. I guess I should just expect it from now on.

Excellent, as always. Just a bit of comparison from the same routes. United has free blankets. Horrible terminal. EWR JetBlue. Updated terminal. EWR. Screens for each seat. Self service pantry and a lavatory in the middle of the plane. Alaska. Always has new planes neon lighting. Mood music for boarding and deplaning. No screens. Outlets yes. Offers water latter part of the flight. Which is nice. Excellent flight attendants. Customer service on phone or gates are always extra polite and friendly.

Correction for previous notes…..poor first refreshment woman on this flight. Second person was great. Pleasant staff. Even got re-seated together.

The first flight attendant who served refreshments was not pleasant at all. No eye contact, no smile, I used my “please “ and “thank you “ and all but had pretzels thrown at me. Next one far surpassed pleasantries and more like Alaska Air! Good leg room, comfortable seats. Boarding was without flaws. I didn’t order food….

All was good. Flight from STS to Burbank was on a new plane; flight back was on a plane that was showing its age.

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

My seat was changed at the last minute and I was moved to the last row, right next to the bathroom despite selecting my seat well in advance. I was also made to check my carry on due to space but when I got on the plane there was significant empty overhead space. Picking up my carry on from the luggage carousel added time to my trip which had already been extended due to delay.

There was plenty of overhead room but half of the passengers were told they had to check their carryon bags. My partner and I checked in as early as possible and our seats were split across the aisle.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

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

I didn’t not like that I could not select my seat and ended up with the worse seat.

The landing was bad and the hostess came two times and i was sleeping but when she served the person that nexts to me I woke up and she didn’t even asked me if I need any drink or snacks two times!!!!

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

Spirit's seating does not work for an overnight flight and my back is killing me. This airline does not meet the minimum standards for being an airline.

All the steps below was great!!! and the price thank you!!

This is the first and last times I take spirit. It’s really bare bones. That old saying that everything comes at a price, that’s really applicable here.

Flight was delayed 8 hours so far. Don’t expect to fly when choosing Spirit Airlines. I will happily pay more to never deal with this company again.

The first flight was delayed which would've caused me to miss the connecting flight. It wasn't the first delay of my overall trip with spirit airlines. They were both due to crew. I was offered a credit after I cancelled my newark flight, but honestly, I won't be flying with them ever again. It's absolutely ridiculous that a full refund isn't given considering it wasn't something mechanical or weather related. It's literally their own crew being late.

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!!!

Doubt that you care, the flight from OAK to Las Vegas took longer on the runway when we arrived. The flight attendants & pilot announced that they knew a lot of us were getting on a connection to Dallas & that it was waiting for us. Lied. Ended up having to take another layover & it’s added way more time to my flights. The ticketing staff at the gates were extremely rude. I don’t think I ever want to fly Spirit again.

Spirit airlines flight delays caused me to miss my connecting flight. I was rebooked in a different flight that routed through Texas. The flight from LAS to Houston was miserable, the person seated next to me was visibly intoxicated, and was served more alcohol in the plane. Upon arrival in Houston nothing was open, even TSA. I had to spend 6 hours just waiting in the airport. All in all, I arrived home a full 12 hours after my originally planned travel which out my family in a bad position. Do better!!!
