The crew was very kind and made going to Hawaii relaxing and fun to look forward to! Thank you Southwest for a pleasant flight!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

We waited in the airplane for over 45 min for a southwest employee to make the flight. This cause over half the plane to miss their connecting flight in Denver. When we confronted the desk upon arrival, they told us the only flight they had was the next day leaving at 8:50 pm!!! Or they offered to get us to Burbank or LA, but after that we were on our own to get back to Santa Barbara. I paid for a flight from sba to bna bna to sba. My re entry into mom mode has been 💯 rough because of southwest mistake with my flight. And now I’m leaving to Reno tomorrow for a vballl tournament and just discovered that my leg in Vegas has me and my 3 kids on a stand by flight even though I had booked these ticket last year November!! Do better southwest!

Southwest is kind of a slum airline. It’s gotten more expensive over the years for less and less service. I am a Southwest Chase Visa card holder and was forced to choose a seat in the 26th row in the middle seat. However my wife who is a rewards member but doesn’t hold a card or anything else, gets randomly assigned a normally paid seat in row 6! How does that work?

For the first time in a long time, the Wi-Fi actually worked the entire flight! The flight crew was amazing as usual.

The seat was not comfortable. 1D. My back was sore all night and the next day.

Great flight. I didn't get a drink because I was asleep whole on the flight.

Great flight from Seattle to Phoenix and to Chicago-Midway from Phoenix

The new boarding process was easy and straightforward. Very pleasant.

The flight was okay. The pilots did an amazing job and kept us updated on the flight. The flight attendants were okay. They found time to be chatty with each other rather than focus on the guests. One of the attendants was a little less warm when asking about my bag I had on my lap that I was using during latter part of the mid- flight. Mind you, it was not the departure descent. I’m respectful to each and every attendant, it was the tone in her voice reminding me to place my carryon bag on the floor. I hope to have a better experience next time.

Didn't like sitting on the waiting pad for 30 minutes right after departing the gate. If you're going to do that, just don't board so people can still get up and walk around in the terminal. My luggage was damaged by the baggage handlers.

The gentleman at the gate I think his name is RIE was exceptional

Loved the crew! Sucks that we went from 1 hour and 8 minute layover to a 3 hour layover. But weather sucks like that.

Everything could have benn better. Short fly, no food, no entertainment and no wifi.

On the return flight, flight attendant Britt went out of her way to inform passengers that several of us had tight connections.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

They told us yesterday APR21st that they were cleaning the plane and we got delayed. After that they said they didn't had any crew for the flight so they cancelled the flight till next day.

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

boarded early to only find out that flight would sit at gate for 45 min to an hour. Landed in chicago and sat on runway for over an hour before got to gate. Total delay was extensive for a 45 min flight door to door.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Really hard landing... as in slammed into the runway then hit the brakes really hard ...

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

My bags were misplaced!!! Im in a foreign country with no bags

The entertainment options on the seat back video boards were nice.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

On time departure and early arrival. Flight attendant very nice.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

The staff was nice. I appreciated that I was able to take an earlier flight, even though it was last minute. The boarding process felt rather chaotic.

Overall a good experience, however Wifi was not working on the flight.

Airlines should be prohibited from using the seats they get away with.

My flight got delayed a total of five times. And the boarding gate changed four times. most of the time the platform was not up-to-date with the changes taking place. The most discouraging part of the entire trip by far.

Flight left early and arrived 30 MINUTES early at the destination. Smooth trip.

American delayed the flight for a crew rest period. The delay occurred late in the evening - the earliest i can find is 10:20 pm. With a 6 am flight anyone on the flight would have already have been asleep (unless you are insane, a vampire or on drugs) and at least for me i was already on the way to the airport at 445 am the next morning when i discovered they delayed the flight until 9 am. Given the incoming flight was in the air at 6 pm the evening before this should have been figured out a lot more timely that was there only crew to use. Just frustrating given there is no consideration for customer experience anymore in flying.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

I didnt have a flight. Kayak must be on drugs because I confirmed with spirit that I had no booked flight.

Spirit is awful, and cost me an extra $400. On the flight to the destination they staff was rude and did not even offer water during the flight. On the return flight, while on the way to the terminal, Spirit cancelled the flight. This is the second time this has happened, and I believe they should compensate for the additional cost for incurred for the return flight. Spirit simply offered reimbursement for their cancelled flight, and did not take into consideration the cost for a last-minute flight home. The TSA agents expressed how Spirit often cancels evening/night flights, and shows no concern for the passengers.

They didn’t put my luggage on my transfer so I had to spend the night in Detroit. They said my luggage would be here in the morning and they’re still searching for it. It did not arrive apparently.

We were delayed and the bag charge fees are very expensive.

The flight was supposed to leave at 6:22pm we are just now leaving the gate after deplaning twice at 1:07am.

Food and entertainment see irrelevant to rate them as that’s not really an option anymore. The flight was fast and friendly. The plane was immaculately clean.

Spent seven hours in the airport with spirit pushing he flight time back two hours every two hours only to then have it canceled without explanation. The employees said, “They’ve been doing this for the last five days.” Would have been great if they told us to expect that when we arrived.

Staff was good! Didn't like how slow the luggage return was

I was waiting in line for the restroom onboard, the flight attendant told me to step back two rows and stay on the carpet. She was rude and I expected a tik tok experience with me getting thrown off the plane. She was rude and frankly there was no where else to stand.

Delay at the gate without any communication such as announcement, sign, monitor, email or text. Found out later we were boarded with the knowledge of a significant delay, awaiting communication from Europe. Pilot was the only source of information regarding the delay after a long gate delay and sitting for more than 30 minutes after boarding. More than 2 hour delay, landing at 2 AM. Offered to deplane and reboard, but probably should have just waited rather than repeat the process. Not the first time experiencing the lack of communication with Spirit airlines. This morning was not as bad as showing up to a terminal without an agent (or aircraft) without any sort of communication. Much later an email was sent that stated our flight was rescheduled for a week later. Situations do arise, but simple communication can alleviate a lot of the frustration. Hard to believe a corporation doesn't understand that. But, you get what you pay for...
