Flight was great, but golf bag never made it until later in the day. Even though I had a nonstop flight it was placed on a different one. They made it right with flight credits and I was able to get it the same day.

Flight was great, but golf bag never made it until later in the day. Even though I had a nonstop flight it was placed on a different one. They made it right with flight credits and I was able to get it the same day.

It seems as though the provisions are even less. Although SWA used to be an economy Airline, that isn't really the case anymore. I paid over $700. for a round trip to Denver and I could have flown just about any airline for the price. The drinks are now in a 6-ounce cup and with ice I'm sure a can would fill more than 2 cups. However, I am very proud of SWA for using paper rather than continuing to contribute to the millions of plastic cups being used each day. I've thought of this fr many years and am so glad to see it come to fruition, if not by only SWA so far.

Exceptional crew! Friendly and professional. Pleasant attitude and treated everyone with respect.

Service was great, boarding and exiting went smoothly, and the flight was very pleasant.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a not a great airport.

Was as expected. Crowed planes. Too many carryons delaying takeoff. But the ride only took an hour and saved me a lot of time SFO is a hell hole of an airport. It is the new LaGuardia. Everything Cobbled together. Security gates closed. Terri directional signage

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

The fluidity of the entire process of boarding the plane the flight attendants attentiveness. The flight attendants also provided coloring books for my kids who loved it.

I used to fly SWA all the time. I know the crew has their little acts that are often fun, and entertaining. On this flight one of the crew was just not nice. Very surprising.

It was really nice! I appreciate the gate attendant allowing families with small children to board early on in the process… that was very helpful! The internet service didn’t work with the app I was trying to use even though I paid the $8… other than that it was great! Oh and I should’ve asked for the whole cranberry cocktail can. That cup was about 2 sips…

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The seats are uncomfortable, feels like a small seat pad on plywood.

My husband is very tall and we generally fly Delta Comfort. We used our companion benefit, and our seats were coach and extremely uncomfortable........ horrid even

My seat had no padding, it was literally plywood with a plastic cover. I could not change seats on my 10 hour flight. My excitement for this trip helped me deal with the pain.

I specifically picked out right side aisle seats because my left knee sometimes needs to be stretched. But my experience this trip was that the seats were shuffled and I lost those assigned seats, resulting in me having to sit in a much less desirable position for my comfort.

I notice that every time I fly delta or any American carrier, the staff seem tired, overworked, and not at the service level I’m accustomed to in Asia. They frequently crash into my arm when coming down the aisle. Food is shoved at my face with no greeting or verbal cue. The food portions seemed much smaller than usual and didn’t see much wine or beverage options. This is comfort plus? The plane was old and tired. The bathroom was dripping with mineral stains after a long lack of cleaning. The power socket did not work, although the USB output did. I really wonder why I’m flying Delta, I think it’s time to switch to ANA.

Other airlines were canceling flights but Delta got us home. Crew was friendly and professional. It would have been nice to have had a little more notice about the delays because we had already arrived at the airport when the first of several delays were communicated but I understand that storm forecasting isn’t simple and we were grateful that Delta didn’t just cancel the flight.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

Screen didn’t play movies, do I was pretty boated the entire flight.

It was very cold because the air conditioner was on high power, and my son got sick.

Long wait before take off without an update for 20 minutes. Flight was good otherwise.

Plane still had screens for watching movies. Good selection too.

The plane’s radio wasn’t working. This delayed the plane for an hour and a half. Then we all broaded and taxied down the runway only to get called back because the radio was still not working. Had to get off the plane and then find another plane making the trip 4 hours delayed. Maybe a different plane should have been chosen sooner?!?!?!

The food for long haul was poor compared to Singapore airlines economy. Pasta plain with tomato sauce . Singapore airlines give me Hagen dash small ice cream cup it was great. The choices of dinner course Singapore air also much better The crew mostly friendly. The economy seat are as expected.

The plane was clean. The staff was excellent. The flight attendants were very good. Enjoyable flight. Overall. The seats in the back are too small but, will always be.

There was no air on the plane and it was very hot.

Flight crew was amazing! I don't like that the Polaris seats are side-by-side.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Flight was 3 1/2 hour delayed with no credit or meal vouchers

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Great flight from Charlotte to Orlando. In flight wifi and entertainment was not working til 25 minutes were left in the flight would be my only complaint.

More room. International flight - by the time you put your purse and shoes under the seat in front of you, add in the pillow and blanket they give you- makes for tight fit.

Boarding can be more efficiently done by having the back row passengers board first. This way, the other people do the have to wait for front row passengers to load their luggage in the overhead cabins. Food is simply pathetic for the price I paid. Cleanliness is simply poor; my seat was full of crumps.

Overall good. Tight connection in DFW because of gate unavailability upon landing.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

No food, no entertainment. But the flight was really short so maybe they had to skip drinks. I was able to board early ONLY because I am old and decrepit and they let me pre-board. I RESENT your dumping us into category 9 if we do not pay up. And when I paid for a seat I was STILL given 9. The pre-boarding helps. THIS flight was exceptionally smooth, please congratulate the pilots.

I love to flight american however my carry on had to be sent with regular luggage and it was broken. Don't appreciate that. If when I buy a ticket says I can take a carry on and a hand item there should be space for mwsy stuff and not be basically forced to send the item even if it's at no charge. A.A. needs to work on that. Everything else excellent.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

Excellent customer service at check in at Austin flight to DFW and excellent customer service from Karren in terminal B at DFW.

Did what they needed to do. Brought us from point A to point B timely and without issue. Boarding through deplaning smooth.

Direct 2.5 hour flight good. Free snacks and coffee, water, or soft drinks not available...bad.

Atlanta airport gate area floor and nearly all seats disgusting. Spirit airlines crew fantastic!!

Over 2 hour delay due to “weather” but all other flights were taking off with no issues. We felt lied to the entire time as well.

Everything was excellent and as expected. The boarding process was great but deboarding was a bit slow. No fault of the crew; it just seemed like the passengers didn’t want to leave! 😂

waited 5 hours to tell us it was cancelled even when they knew

Easy! As long as you don’t mind no frills, our flight was enjoyable and on time

No carry on available to purchase at any point, charged for water, no power to charge phone. Other discount airlines have this.

Okay for the most part but Good boarding and on time

The flight was delayed and the announcements were hard to hear, but the crew was great
