We were delayed for hours and this was very difficult, which is why the experience was less pleasant

They were friendly, efficient and got our bags to us so fast at the end of the flight.

The most comfortable plane ride I’ve had in quite a while.

always delayed. toilet is too stinky worse than smells in sf homeless distriction

It was a quick flight, but coffee would have been great!

Get more efficient check in staff. My boarding pass was printed with different name. My son who was traveling with me had his boarding pass printed in duplicate and we were interrogated like it was our fault that I may have lost my own boarding pass when the staff knew very well she just handled and tore the piece she need. This was with PAL.

In GEG I arrived at 0930 for a 1600 flight. Alaska had a rule that you could not check your bags until 4 hours before flight time. I was forced to sit in a chilly lobby for hours. I had access to a bathroom, but could not go into terminal for food and drink. Boarding and flight OK

Flight was delayed by hr and half, takeoff and climbing was frightening

Hire more people. It’s not my fault they don’t have enough pilots. THEY shortened my vacation, by changing the flights I booked. We sat on the tarmac for an hour. $35 for my checked bag, and then they wanted $75 MORE for me to pick my seat??? A tiny bag of pretzels on my connecting flight, with nothing on the first leg. Big deal. The people were great. Can’t deny that. But the way they do business, leaves a bit to be desired. They are just another airline.

Missed connection due to waiting on tarmac for gate. Rebooking took 30 minutes in line with 2 people in line in front. Horrible inefficient careless staff.

southwest just starting charging for luggage. hadnt realized it until it was too late. now out $70 when i couldve bought a carry on if i wouldve known. free bags was one of the only reasons i chose southwest over another airline (the other being no assigned seats, which is apparently also being changed). stupid business decision. wont be flying southwest anymore.

The quality of Southwest Airlines continues to degrade each time I fly with them. If it were not for the free luggage, I would probably choose another airline. Their prices are a little bit competitive, but way too high for the quality of the service. Southwest is not unique in this way. Domestic flight in the United States of America has continued to be a lower and lower quality product. Very sad when you compare the quality of domestic airlines to that of many international airlines around the world.

Very smooth checking in our luggage with a super pleasant SW agent. I enjoyed a fun entertaining movie.

WiFi did not work. For as outrageous as these flights cost, when they’re advertised with certain services/ features they should be in working order

Worst experience I had on Southwest. Still better than most, but the seating was barely tolerable.

The Southwest employees (all two of them) were very nice and cheerful despite the fact the line to self-check a bag (simply drop it off) was hundreds of people long. Thank God I arrived early to the airport because I stood in this line for at least an hour. Once on the flight that had been delayed by an hour, we had no Wi-Fi and thus no entertainment. Finally, I hope the investor strong arm tactics against Southwest pay off in a short-term windfall to your C-Suite because the rest of you are screwed. I have been a faithful Southwest customer for 15 years due to everything you just got rid of. I'm flying to Idaho and Washington in October, both places I used to simply book with Southwest without a second thought now with Frontier (Washington) and United (Idaho) because they offer everything the "new" Southwest does but cheaper and at better times, destinations, etc. This really makes me sad...

It was okay. The plane was delayed from earlier in the day, but they kept updating the departure time, sometimes later, sometimes earlier. That was stressful. Once we finally got on and took off, it was fine. I was supposed to have a connection in Chicago to Los Angeles, and the time for so late I was rebooked to arrive in LA 3 hours late. The departure time to Chicago later became early enough to have taken my original connection and arrive earlier but that wasn't an option.

It was one and half hour late... Not sure if any other experience matters.

Delayed flight. Nicest crew member was a SW pilot flying seated next to me who kindly move to seat the final passenger. Flight extra delayed. My cup of refreshment of ginger ale was so packed with ice it was literally 2 sips.

For my birthday trip this was my second time ever flying, this trip was the best.

Delayed and took off even later than the scheduled delay time

For a 69 year old with health problems I had the worse experience, no wheelchair when I entered a lady told me to sit and wait while a gentleman told me I had to walk to the Delta station, which I did. I had a carry on and a bag, and I was traveling with my service dog, which was on his carrier and the lady charged me for my carry on luggage, beside all the waiting cause of the delay, I had to walk to get my luggage cause no wheelchair showed up, I am so disappointed. I will get in touch with the company. I got home at 3:00 am, not good for my health situation.

Great experience on Delta. Staff from baggage check to flight attendants were very courteous and professional. My only issue was a personal preference for pretzels instead of the chips and cookies that were offered.

There was no problems, just a little uncomfortable with seats that do not lay back a little

Always good but we must do something about people in rows ahead of you that don't put their seats back up when they are suppose to. And It's rough to not be able to even lean over to get something out of my purse.

Flight was delayed, 30+ bags had to be gate checked. Crew were very friendly!

Everything was good until we were boarding our connection flight in Atlanta, we were told to gate check our carry-on, but when we got inside the plane, there was plenty of room in the overhead.

Did not know my son and I had different seating arrangements. He was fine, but it was disappointing.

Flight was canceled, and no effort was made to help with rebooking, no hotel vouchers, no car transportation and minimal food voucher and most places for food were closed by the time the voucher was given. Waited for 3 hours for bags. Simply the worst travel experience I have ever had

Food was surprisingly good but the WiFi was not great

It was canceled. The flight wasn’t rescheduled, everyone had to figure out their own new arrangements. They said we would get refunded our original fare and receive an additional $150. We received links for $100 only and they expired before we could activate them.

The plane had originated in Las Vegas at 6:30 in the morning and flew to Moline where we boarded. The flight left around 12:30 PM and there were no boxed snacks available and many of the alcoholic beverages were unavailable. I would find it hard to believe that that many of the passengers coming from Las Vegas at 6:30 in the morning, drank and ate that much of the items. I can only come to the conclusion that someone failed to stock the plane for the round-trip. This is a huge revenue failure for the airline and disappointment for the passengers. The flight crew did not seem happy to be there and did not engage with passengers. Allegiant you can do better.

They did not let my husband on the plane with our service animal at the last minute. Do NOT fly this airline with a service animal!

Tight! Seats are not designed for those of us who wear extra-large clothes.

The non-stop flight from Grand Rapids was excellent. I neither expected or needed a budget flight and Allegiant made the trip easy and for an affordable price, Arriving at the Mesa Airport (AZA) is a delight compared to the international airport. For our return flight, we were able to arrive 75 minutes before the flight, return the rental car, check our bag and make it to the gate in plenty of time. That would never happen at most airports.

Easiest flights I’ve ever taken. Plane was comfortable without overly crowded seating.

Terrible. Still have not received the refund from them. They sent it to some account that I don't even know. Spoke with costumer service and they are unable to help.

I didn’t like it at all. I miss my second flight because of the delay on Allegiant Air now I m stuck in MCO.

Good, but a bit late on take off after loading. Don't like charging for carry ons!

First time flying with them and will definitely fly again in the future. Crew was so nice and friendly, fought was seamless. They are simple planes, no entertainment, but it’s fine for a short flight or if you have personal devices Rates are competitive, and they did so well with keeping the flight on time after a tropical storm, where other airlines had delays and cancellations.

Late departure by 1:45min. No explanation why. During boarding inconsistent policing of their baggage rules. Before takeoff and lamdimg strange obsession with window shade and armrest positions. Don't know why they care. 15 min tarmac delay on arrival, they blamed airport congestion but we were the o lh flight waiting, it was clear it was due to poor staff planning (only one ground crew to receive airplanes and multiple arrivals) Got there but was rrally lame the whole trip.

One of worst experienc my family have every had with this airline. I was informed my Kayak that my flight was delayed and that my family will not make it to houston for our connecting flight. I contacted Spirit customer service to get my family on a later flight due to the delay in Vagas and them not making their connecting flight. The customer rep keep telling me that the flight from vagas is on time and not delayed. She even make to go to the spirit app on my phone and show me how to look up weather or not the flight was delayed. The app showed "on time" 20 minutes later when my family arrived at the airport for their flight, they were told that the flight was delayed and she will not make her connecting flight. I call spirit airline customer support again that night and spoke to another rep who apologize for his collegue and he told me that my family will receive a credit for this, this was on Saturday I still have not received the credit or an email letting me know when I will be credited for this inconvenience. This is not good business and it need to be fixed.

Flight was cancelled. No reason given. No apologies. Next available flight is two days later. Ruined our 4th of July plans.

Flight delayed over 3 or 4 hours because no captain to fly plane. I couldn’t make a connection and had to wait 9 hours for another flight. Had to fly red eye flight. Sucks

We paid for upgrade seats (3A & 3B) the seats on front and the seats behind us got complimentary water & soda, but we got charged, had to pay for everything. Does not make any sense ?

Horrible considering I didn’t go and I bought travel insurance and I didn’t receive a refund.

Spirit gets you there; it's no worse than any other aircraft, all things considered. (It's not like everyone else is such a hero). But - holy moses - do they nickel and dime you to absolutely every nickel - I was really expecting to have to pay to use the bathroom. And when the captain comes on with a 5 minute sales pitch about getting "points", that was like something on Bizarro world. Other than that, everyone else was professional and worked hard to get us from point A to point B. I'm not loving all the "self-service" stuff but there it is - just when the machines don't work you don't have anyone to talk to.

The ease of booking the flight was very good. Speaking with customer service was also good. However, the crew people are unfriendly and unwelcoming which I found this as unprofessional. As far as comfort it was mediocre. This was my first time flying Spirit and I chose them because of the flight times met my needs and my budget. However, I would be reluctant to fly on Spirit again. In addition, if the crew were more friendly and at least appeared somewhat happy and welcoming personally it would probably make the experience of flying with Spirit better.

hahaha we are delayed for one hour plus.. but thx we arrived San Diego safe

Canceled my flight and refused to put me on a different flight to get me to my destination. Unacceptable and ruined my trip
