It was much better than expected. Short flight and smaller plane so no entertainment or food.

It was much better than expected. Short flight and smaller plane so no entertainment or food.

It took around two hours to depart. Just sitting in the tamarack waiting. It impacted my traveling plans in a very dramatic way. When we returned, it took around two hours for us to be able to get our luggage. Ridiculous!!

I thought every thing was good with the acceptation of the long layover between Seattle and the Tampa trip.

While the flight and the legroom was good boarding took a long time. The different groups Boarding made no sense as those in the back of the flight boarded last causing delays as people try to find room for their luggage in the upper bins. While there were plenty of seats on the flights We were spaced so that some rows were filled and others were empty. My first flight was very crowded and uncomfortable. On the way back both flights did not have Wi-Fi nor the entertainment package. We were only made aware of this a few hours before the flight. Since the flight was in the morning, I was asleep and was not able to download Books or other media to my phone. This is my first time flying Alaska airlines and I will admit to thinking twice before I do so again.

Our flight was delayed by six hours, our plane never left Portland the night before but the airline didn’t inform anyone till two hours before a six am flight. The plane, our plane never left the west coast! No plane no flight, simply let folks know when you know, not hours and hours later. No one apologized, no one said much of anything, we were just expected to wait quietly and await instructions.

The staff were great and the layover times were excellent no multiple hours. I just hate the Boxed Water. So you really have to purchase high price water in the airport.

Both flights were delayed. We sat on the tarmac on Boise for 3 hours with little updates

This flight was significantly affected by poor wifi connections. I couldn’t get my work done because the wifi kept dropping. Even texts were not going through. There is no seat power in premium class either. I fly a lot. Today was my 10th flight in 4 weeks. This was by far the only flight that was sub par.

4 out of 4 flights cancelled or delayed. 5th trip with similar experience

On time, comfortable seats with plenty of leg room, nice staff. Pretty good!

Delta is one of the best airlines I have flown

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

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!

I appreciated being upgraded. I was very disappointed with my 13 hr layover in Seattle to geg, while my friends who flew Alaska made it home as scheduled. I had to reserve a hotel on my dime.

Delta needs to step up the meals and snacks. They have been serving the same two meals for three years.... It is time to change it up.

This flight is frequently delayed. The connections seemingly are more frequently delayed. I’ve missed connections as a result twice on the same route to charlotte then Charleston. Final destination arrival has been the next day, twice in a row. No pilots, no crew. Too many excuses. Unfortunately, my days with American are over.

Entertainment was okay not because anything was wrong but it is a short flight so having no wifi is annoying but understandable. Crew was outstanding as usual

Those seats were way too narrow. I had the middle seat, one person was a very skinny person and we still couldn’t avoid touching each other anytime one of us moved. The other person was larger and we were basically sitting in each others lap the entire flight. There was zero entertainment. The flight was long enough to justify tvs, but no. Gotta sit there in your infant seat and twiddle your thumbs.

The Flight attendant had an attitude and didn't allow anyone any time to prepare for landing despite being absent throughout the entire trip

Flight boarded without pilots. Sat on plane for 3 hrs. after over an hour late boarding. Plane never took off. Had to deplane near midnight. Line for rebooking was 3 hours + long. I had to leave.

The flight was great but board was a nightmare. The gate was changed 4 times during the layover period

The experience was great and much better than the flight going out. of course I was in first class but the service was excellent

Cold air blew constantly on my legs almost making me numb.

Missed the flight because of them and up geting a rental car

Delayd flight out of atl as always miss my conection in dfw no flight untill next day

Not much seat room, but that was unexpected. But the seat headrest was very uncomfortable.

First the good, everyone was friendly and efficient. Flight was smooth and plane was very clean and new. Now the bad, seats have almost no padding on your behind. I was in exit row so I had tons of leg room for a 6' 2" bean pole with long legs. Everything was extra - water, soda, snacks everything besides oxygen. Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries.

Ya get what you pay for, and my flight was cheap as you could ever want it, so no worries. They dont really bother you about carry-on size, I brought a descent sized backpack and they didnt even check.

Spirit canceled the flight in March and never notified me!

Seats suck, not enough room, overcrowded planes, hectic situation all together.

Pretty good. Would’ve been excellent if we would have left on time and the crew wasn’t late.

I do not like the customer service, I had an emergency and needed to cancel a pet reservation right after I had booked it and they would not do anything but issue a credit. I haven't flown in years as I have 7 kids and don't have spare time. I want my $125 back on my card please

Spirit airline tries to screw you at every opportunity. Spirit wanted 65$ for an extra pound in the suitcase Made me open the suitcase at the counter to remove 1 pound. Staff very cold and rude Will never fly spirit again and will recommend same to family and friends

Delayed..4 times...completely disorganized boarding. After 5 hours they scrambled to move ppl off plane bc they overbooked. Then they didn't have a cabin crew. WiFi on plane didn't work. Zero amenities. Once we boarded we sat on tarmac for an hour. Explore all alternate options including purchasing a pair of hiking boots and walking to your destination instead of flying spirit.

what I like about Spirit is that the pilot and crew are good communicators. The plane itself - well, its a budget airline and you get what is expected, But I generally just feel safer, somehow, when I know more about what is going on - and Spirit has always done a good job of telling me what is going on: why the delay, why the turbulence, why this and that... and that means a lot to me.
