The entire experience from boarding to landing was amazing! The crew were very friendly. Will definitely be back.

no service at all due to turbulence. they should've at least given us snacks, there were only 10 people on the entire flight.

First time I've had to use the disabled accommodations. And I could not have had a better experience with Southwest, i was having trouble getting from one terminal to another due to my heart failure. And the next thing I know a Southwest agent had made sure. I had a wheelchair at all my flights. Can't thank them enough.

Delayed flight, lack of information, boarding process is a mess as is the carryon luggage causing issues when leaving the plane….just a poor experience.

Comfortable. Easy. No problems. Just wish they had gf options for snacks.

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.

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

No entertainment. Plane was so small had to pink tag a carry on ive used for 20 years easily on board. The fact the flight got in at midnight, had to wait for crew in fort wayne to allow the plane to approach the gate, THEN had to wait for bag on jet bridge made experience irritating at best.

Overall Good! The weather delayed our takeoff from Atlanta and our arrival in Miami! If Mother Nature can mess up a flight she will do it every time!

Subpar. The seating on the plane is almost unbearable. We are literally touching and/or sitting on each other which is totally unacceptable and shameful. Pilots and crew was very accommodating and friendly.

During the flight, the only refreshments provided were crackers and soft drinks; no substantial food was offered despite the international route. Furthermore, our initial flight was delayed, causing us to miss the connecting flight in Atlanta. The airline did not hold the connection, and we were informed that the next available flight is not for another 24 hours. While I am aware of alternative options via JetBlue, they operate out of JFK, which is not a viable solution for us as a resident of New Jersey.

Mechanical Delay of over an hour with multiple gate changes. Entertainment system down for rejuvenation.

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

Same experience as the flight from Norfolk to Atlanta where people are boarded in zones that don't make sense. People behind you on the plane will get on before you and they take the luggage space on your row.

I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

two hour delay and the Delta representative on the PA system was unable to understand

Flight was as expected. But it was delayed an hour. Also, my luggage got damaged. So that sucked especially since the damage made navigating the airport difficult. Walking to get ground transportation is sooo far away now and my checked bag was difficult to carry.

Flight team was very courteous only complaint wS the boarding process and mandatory bag check

It was a great flight got here on time wish they would give headphones out for free

The flight was delayed 4 hours and the JetBlue people at the counter kept lying to us and telling us it was due to weather however all other flights were going in and out of NY and FL. Then they lied that the plane had to stop to refuel. Then they lied and said the plane needed a tire change. JetBlue is the worst. Then they gave a lot of people meal vouchers however I didn’t know they did that and they didn’t offer anything to me.

Disaster This is why I stick to delta You get what you pay for

I had a great experience flying with JetBlue and would always choose JetBlue over the other airlines. I am also very bummed that they will discontinue flying to Belize very soon. SAD

I was traveling with two small kids and our TV s were the only ones not working. Informed the flight attendant who did nothing about them.

I was especially impressed without efficiently the crew got passengers on and off. One of the stewards was slightly gruff, I thought. No big deal but that's what I noticed.

Delayed our flight to accommodate another flight but didn’t make the decision to do so until we were supposed to board despite having all the same information hours prior. Arrived so delayed that we didn’t get a gate and had to deplane on the tarmac and get bussed to terminal in the rain after 1am. Arrived to the terminal and due to construction could not get a ride share - had to either take the air train to Howard beach or stand in line with 200 other people waiting for a taxi.

Well, its a hit or miss when boarding most of the time your employees just let everyone enter immediately In one bum rush. Then out of know where tell the passengers only let A can enter then b then c etc. So make a decision and stick to it. Do it by alphabet and have famn strick compliance. Let the public know. That makes easier on passengers.

Boarding gate at LAX was too crowded—two gates next to one another

This was a hard flight. 3 delays out of OKC (1 on the Tarmac). Delay in Atlanta coming to Dallas. total travel time was the equivalent of driving from OKC to Atlanta.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

This short sector between Miami and JFK was undertaken purely for business purposes, with efficiency as the primary objective rather than a full inflight experience. Overall, the journey met its intended purpose; however, the ground experience at Miami stood out significantly. During check-in, I was unable to link my frequent flyer details from Qatar Airways (oneworld alliance) through either the self-service kiosk or web check-in. The situation was handled exceptionally well by the check-in agent, who demonstrated remarkable ownership. She coordinated across multiple counters, ensured my frequent flyer number was correctly reflected, reissued the boarding pass, and confirmed that mileage accrual would be recognized. Additionally, she ensured the boarding pass reflected priority status, enabling a seamless priority check-in experience without delays. This level of proactive service was both commendable and impactful. Boarding and the inflight experience, operated by American Airlines under a codeshare arrangement, were efficient but largely transactional. While operational delivery was smooth, there was no visible recognition of oneworld frequent flyer status onboard. In comparison to the consistently personalized engagement typically experienced with Qatar Airways, this absence was noticeable—though understandably a potential limitation of codeshare alignment rather than a direct service shortfall. In summary, while the flight itself fulfilled its operational intent, the exceptional professionalism and commitment demonstrated at the Miami check-in counter was the defining highlight of this journey. Greater consistency in elite recognition across partner airlines would further enhance the overall experience.

I almost missed my flight and they helped me out enormously

Flight was fine, but not having WiFi was a major negative

Very disappointing. Flight was delayed by 1.5 hours and food options are very underwhelming even for first class seats (same food given to economy seats)

Everything was excellent and I enjoyed myself. Thank for everything

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

We left at 1030 am pacific from LA and supposed to land at 7 pm Eastern in NY. They made a detour, stopped in Philadelphia and didn’t land till 1130 PM Eastern!!! Worst flight experience with no pilot communication with no explanation as to what was going on. Everyone was very frustrated to say the least.

Plane was hot and miserable and the crew was rude!

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

They didn’t offer a water, even after I asked

They switched our terminal 3 times and we were delayed for four plus hours!!!

It was an early flight and most people napped/slept and the crew let us which was nice.

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.
