we were late due to plane's late arrival at the gate and then there was a glitch with a button or something that had to be fixed and we waited for a tech to do that . The flight was very bumpy and totally not anything to do with the plane or crew. Just saying what was a bit miserable and kind of worrisome give then recent circumstances with the planes. Nothing fell off or onto anything during the flight of take off and landing so I count myself lucky to have gotten to my destination there and back safely. Thank you for asking

I'm a tall guy. Fortunately I was able to find seating in the emergency rows that gave me a couple more inches of room. My return flight a few days later, I wasn't as fortunate. Very painfully and uncomfortable return flight.

Flight was smooth but to many screaming and crying young toddlers who wouldn't stop crying and screaming at the top of there lungs it gave me a bad headache.

They misplaced our 1 bag and that messed up our reservation for the following day of fun and we paid extra 100 for the bag. Not fun

Crew was friendly and professional. Offered multiple drink services. Handled this full flight with style and grace.

Horrible, missed my connecting flight because Alaska did not give me enough time

Great crew. Uncomfortable cramped seats. Crappy snacks. But on schedule and no doors blew off.

Everything was great until one of my 4 checked bags didn’t make it with me. Baggage staff at OAK were not especially congenial the first night. Got my phone number wrong so they couldn’t reach me via phone. I was able to pick my bag up within about an hour of when I initially wanted to. Wendy was very helpful.

I was on a ski vacation and traveled between Pittsburgh and Big Sky, Montana via Seattle I was very disappointed that I couldn't reserve a seat between Seattle and Big Sky ahead of time and angry that I had to pay a fee to get a seat (both ways) when I checked in online. Why couldn't I select a seat ahead of time for that leg of the fight? The flight itself was fine and the seat was comfortable. On arrival back in Pittsburgh, I waited over an hour for my skis to arrive after I retrieved by boot bag from the carousel. This was my first experience on Alaska Airline and it was disappointing.

One of their flight attendants made a rude comment as I deboarded the plane. Definitely won’t be flying with them again.

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

Flight was on time, the crew was personable & professional, & the plane arrived early which was nice.

This flight landed early, but deplaned late. We were stuck sitting and waiting for a gate for over an hour

My flight was very clean and the location was comfortable. The service was great. A satisfying flight!

Really liked the choice of the 4 free snack options. Crew great. Good vibe on plane.

More filling food and more entertainment options would be cool.

There was no wifi even after my husband paid for wifi it wasn’t working. The plane looked and felt old.

Flight and seats were great. Food service was average at best. The real main problem we had is that we got cheeseburgers for the kids but the plates was extremely hot. Like ridiculously hot and the stewardess never said anything. Luckily or unluckily my wife touched the plate and was able to deal with it before the kids got burned.

Flight was on time. Staff were friendly. I paid for Economy Plus but was required to check my standard carry-on luggage due to lack of space on the aircraft. This cost me 30 minutes, unexpectedly, in waiting at the baggage claim. This experience did not meet my expectations.

737 Max was leaking water into the cabin through the windows. Overhead bins opened on landing. Bad bad plane.

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The plane boarded and deplaned twice before the crew timed out. Flight was 7 hours late departing. Horrible experience!

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

Everything was very good. Boarding and takeoff were on time and organized. Had a good flight

Wouldn’t let me check in said couldn’t find a ticket had to wait very long Time

Awful…flight was delayed more than 12hrs, missed all connections to Fort Wayne, IN, had to get flight to another city 2 hours from my destination, flight was again delayed by 40 mins because they did not have enough fuel, again missed a connection, finally arrived in Indiana at 11pm…but before my 2 hour drive home, ay, no Five That Our Luggage Never Made On The plane and Still In Chicago

Other than the two hour delay, it was fine. Of course they were very professional and kept us informed throughout the whole delay..

Wheelchair assistance was not complete. The person left me at the departure gate without informing the groundstaff of my requirements. I had to walk to the departure counter to ask for help to reach the plane door. The crew informed me that in future they were not allowed to help passengers like me, senior citizen and Wheelchair passenger with placing their carry on bags in the overhead compartments!

The 2 hour delay was frustrating but our crew did a great job getting us out quickly and keeping communication especially with the people who had connecting flights

Got a much appreciated surprise upgrade to an exit row and the crew was very friendly and helpful.

The only problem experienced was a ground stop in Chicago due to weather. But the crew handled everything professionally. They prioritized rebooking those passengers who had connecting flights and then deplaning the other passengers. When the hold was lifted, they efficiently re-boarded all the passengers so that we could depart before our departure limit expired.

The staff was unprofessional and didn’t communicate very well. The boarding process was very disheveled, potentially due to a power outage the previous day but there was no contingency plan to properly get passengers boarded the following day. Once boarded the aircraft stayed on the tarmac for over 45 minutes due to high winds. The communication was sporadic but an announcement was finally made an additional 30 minutes later that the flight was cancelled but we couldn’t get off the plane. Prior to deplaning one of the gate agents came on the plane and made an announcement for everyone to pickup their checked bags and take a card to rebook a new reservation because they didn’t have adequate staff. Flights were missed, passengers went to different airports and there was little to no assistance from AA.

Absolutely filthy flight and not equipped for a trans US

Everything was on time; the flight attendants and the gate personnel were very pleasant and helpful.

I had trouble finding a boarding pass because I had an hour between Flights and American did not see my flight I believe because I was ticketed through KAYAK. I did not have enough time to go to the desk before boarding so I went to the desk and told them while I was boarding and they had a boarding pass for me within three minutes. Nice. I paid extra to have more legroom and it is definitely worth it for a six hour flight. I would’ve paid for a decent dinner, but they didn’t offer anything but a snack box —not good for six hours.

I have not found it to be easy to set up on Wi-Fi with American Airlines. I don’t know if it is me or poor instructions.

My previous flight was late and did not connect properly. The gate was closed and I missed this flight.

This flight was late and did not meet the connecting flight.

Delayed several times. Flight was to arrive at midnight and it arrive at 3 am. A 3 hour delay is already bad but one that has you arriving in the wee hour is just disruptive and overall unacceptable. The complete lack of restitution is a joke in keeping with Spirit’s reputation of ranking bottom-low in the pecking order.

Awful experience. Both flights were delayed several times with weather but also crew members being the official cause. The vouchers are unusable and insufficient ($50 voucher to fly the same crappy airline is a joke for putting me on a red-eye that landed at 3:00 am). The aircrafts were old and uncomfortable (have a real pocket on the seat, for crying out loud!).

Its so random that they only allow 40 pounds on checked bags when all airlines take 55. They then charge you for each 10 extra pounds, so my checked suitcase was $130 and the flight $30 ... its like whattt, im for sure not traveling with Spirit again

Cancelled my flight last minute and had to end up driving to Texas from Atlanta last minute. I’m going to miss another day of work, drive back to Atlanta , in my own car and spirit doesn’t want to refund the money. First time I tried flying anyone else but delta and I get ripped off . And I had. To pay for seats for a flight that didn’t happen. Usually you could say you get what you pay for but in this case, didn’t get anything and paid for everything never flying spirit again, or even attempting it or thinking about it.

Don’t fly with Spirit unless you wanna be treated like trash. Racist employee too

Was not able to board the flight due to a horrible policy that I needed to be at the gate 1 hour before departure. I lost money on this and the connecting flight due to having to book on another airline. I was flying to Florida for my mother's cancer surgery in the afternoon.

Great flight on time and kept us informed about our flight situation!!

flights were both good to and from. in flight seats were uncomfortable but ok for a short flight. flight attendants were very nice.

Very bad. Plane delayed. Crew not nice. Luggage weight limit is 40lbs and they overcharge for over weight

Offering free water, tea, or coffee for longer periods of flight
