I have roller bag with food and medication told me I couldn't bring on my 2nd flight today. 15 years flying with SW never an issue with that bag.

Southwest continues to do less for more money. Flight attendants used to be fun and friendly. But now it’s like they don’t even see you. Such a shame.

Great flight. Good snacks and drinks. Grateful it was free. The flight from Nashville to louisville, i think her name was Tracy (not sure that's right) super awesome, nice and cheerful. She really enjoyed being at work today! She was the person who scanned the boarding pass on flight wn941. She should be recommended for a raise !

I liked it better when you were truer to your roots Am paying more for less fun

We had a 5 hour delay on the tarmac in Baltimore

Long layover between flights to Long Island from BWI - need better coordination between flights

I elected to pay for the upgrades and found very little difference

The last 3 flights between BWI and BDL canceled the beverage service mid- way. Just say up front that the fight is too short. Thanks!

Flight was hours late, unable to sit next to spouse, I have had so much better experiences. Substantially better, only saving grace was that it was a short flight.

I was assigned seat 7E, yet my boarding was Group 5, which caused me to have to put my luggage in the back of the plance above `19 or 20 aisle, as passengers who had boarded earlier took the overhead bins in the front. SW needs to monitor bin space and ensure that bin space above the seat are aligned to those sitting near their seats. Also the seating assignments needs to align with group number. Maybe board those last first and so on? Having said the ALL the passengers on the plane were gracious enough to allow me and other passengers in this dilema to retrieve our luggage and helped us along the way. I always love the flight staff, as always their fantastic and I can't rave about them enough!

The flight was delayed 90 minutes The Gate was wrong The Restroom on Aircraft was not clean There was a half used water bottle in my seat

Delta is always a wonderful experience. A clean plane and the crew is really friendly.

Too many people are taking up space in the overhead bins with their extra piece of luggage. Since they cannot fit their backpacks or extra luggage piece under the seat in front of them, they store it in the overheads and thus taking up room for other passengers. It wasn’t only one or two persons; more like 12 or 13 passengers.

This was the worse experience. They delayed our flight twice and we still had to find another flight to get home sooner which was alos delayed. Also, the flight attendant named Ginny on DL9890 leaving at 4:13pm on 3/23/26 was extremely rude.

I love Delta the flight attendants were personable and the flight arrived 1/2 earlier thanks expected. All a plus. The gate agent was a bit flustered but even with that I still had a good experience. Her supervisor assisted me.

Got to fly my favorite plane, the Boeing 767-400ER, to Milan. The soft blush pink mood lighting during meal service was very beautiful and gorgeous. The service was top-notch, and our flights were on time. I highly recommend Delta.

I am still at the Airport! Delayed Delayed and Delyaed

I took seat 15A in anticipation of window seat, there is no window.

The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

I've been flying American mostly, and it's been very frustrating. This united flight makes me realize maybe the issue isn't flying, but the airline. United was a significantly better experience. The plane was more comfortable, with a normal amount of leg room (vs the ridiculous reductions AA has made), more comfortable seats, screens to watch movies. It was a much better experience!

We had excellent customer service despite the chaos at George Bush airport in Houston!

It isvvery small flight. No leg room . No space to put my personal item at feet.

Didn't make the flight because the first leg of my flight was canceled and the next leg was already booked.

Terrible because it was cancelled due to volcanic ash clouds in Guatemala while all other airlines kept flying. Had to pay for a hotel to stay overnight in Houston and try to fly next day.

Overall we had a good experience during our flight from San Francisco to Houston.

Airport terminal was outdated, flight was on a small jet with no wifi

The crew made our experience extremely bad. They were rude and didn’t have anything for kids.

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

Flight delayed twice (not Spirit fault) No food served* No entertainment * *in response to my choices in the rating. None was provided so couldn’t rate properly

we boarded the plane and then sat for OVER AN HOUR on it, first waiting for fuel and then the crew timed out. the flight kept getting delayed longer and longer, a 9:30pm flight is still on the ground at 1:15am.

Delay due to personnel issues on Spirit’s end. Original departure time 9:30pm. Took off at 2:15am. Lost an entire night’s sleep bc Spirit couldn’t get a crew together. Very poor.

First off, I had a conversation with a flight attendant that was working this flight. I overheard her telling another flight attendant while we were in line for Chic-Fil-A that the flight was not going to land until 12:47 pm. I found this odd since the flight was to take off at 1:03. I commented to the flight attendant that was going to mess up the on-time take-off She said. if you fly alot you will notice that it's a good thing if the flight even arrives at all. I said that was a low bar. I think that flight attendants represent their airlines whether on board or in the airport ordering food. I was surprised to hear such negativity. However, I have noticed that Spirit flight attendants are usually in a sour mood.. Eventually the flight arrived and I boarded and the flight took off an hour late. There was no direction about the on-board wi-fi. Nor was there any info in the seat back pocket. I don't know if there was wi-fi or not, There were no complimentary snacks or drinks for my row 36 as there was turbulence and the captain asked the flight attendants to stop serving just as they were close to my row. When the turbulence stopped, they did have time to serve us but they did not. Upon arriving, the flight attendant asked anyone not having to catch a flight to Ft. Laudersle which was a tight connection to sit down and let those people pass. I complied but I could not help thinking that if Spirit would have took off on time that they would not have to inconvenience their passengers. All in all, I think Spirit is a mediocre airline at best. There are so many things they could do to improve. Yet, since I only fly Spirit infrequently preferring Southwest and Delta, I like to see if they are improving and sadly no, they are not. One good thing - nice modern seats and interiors.

They charged late fees for selecting seats (no $0 options). They also changed my gate within the last half hour and are refusing to reimburse my costs to drive across the country with two small children in a rental car.

the fligh was delay form 9am to 10, delayed again from 10 to 11, than delay and gate change to 12 and delay another gate change to 3;25 pm

I purchased extra legroom so I will be comfortable but the guy behind me is a big guy who keeps on moving and since he is big I can feel his movement at the back of my chair.

Flight was cancelled with very little notice. Had to scramble to find transportation to my Mexico vacation.

Every Spirit flight we took was delayed by nearly 2 hours. We arrived in MCO and learned that our connection had been canceled. There were no options for rebooking for 4 days. No hotel vouchers provided, no transportation etc. The airline essentially stranded us, and rhe passengers from 6 other flights hours from our destinations with no assistance. Still no word on my refund. Terrible customer service.

AWFUL THEY CANCELED MY FLIGHT LESS THAN 12 HOURS BEFORE AND GAVE NO WAY TO GET A REFUND OR BOOK A NEW FLIGHT. THEN HAD THE AUDACITY TO GIVE ME A $30 VOUCHER ON A $500 FLIGHT

The crew acted like they had never done this and kept barking passive aggressive orders at people. + the security line + the delay + sitting on the tarmac for 2 hours + none of the apps or signage updating with correct times

More inflight connection. And leg space is horrible. And the paying for baggage I'd ridiculous!!!

My flight was originally from SAT to MCO connecting from MCO to ORD. We got diverted to ATL and than Frontier staff there was sooo un helpful first they said they couldn’t give us any accommodation since our flight first got delayed that cancelled and now it’s 221am and I am still in ATL since they said they need to create a new flight my final destination is ORD and I have been delayed twice and cancelled. With no real help the frontier app didn’t work no email updates over all such a horrible experience

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!
