Easy to book and to get check in and get on and off.

The last 30 min or so, they put the heat on full. We thought we were being basted.

Excellent experience. WiFi worked on this leg of My trip

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.

Crew was nice. Flight was timely. Seats could be better as well as the food considering it’s first class.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

Good and consistent Printer in lounge did not work for me :(

Most of my discomfort was going through TSA. However, the Delta seats had inadequate leg room and I tried my very best to connect to the wi-fi and it was a cumbersome process that finally gave me the info that I needed to sign in AFTER I had completed the flight...Why make it so difficult to use? That said I really really appreciate the pilot taking a little extra time to avoid a bad storm area and both landings in Atlanta and Orlando were flawless to my delight!!!

Delayed in taking off because no flight crew. The in seat entertainment was working properly.

I upgraded to first class only to find out that I still had no access to the sky lounge without a sky miles card or AmEx (something that should be emphasized outside of the fine print!) Also, no food or drink service provided during the flight, so I basically paid 4x more just for “free” checked baggage and a bigger seat. Not worth it.

Delta was really good about being transparent with why we were delayed it’s just that’s the plane was really old and outdated and a lot of the comfort and amenities we know Delta to have did not shine through

Bottom seat cushion is almost non existent. Very uncomfortable seat.

Delta was great the entertainment was outdated.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

Flight did not have seat back entertainment and the wifi was iffy.

My seat was very worn. Otherwise I had an excellent flight

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

Checked in the minute I was allowed and still wound up in group 8 for boarding.

great experience. minimal lines at BWI. at DFW they got a long haul 787 boarded in 30 minutes

Overall flight was as expected. It would have been better with a couple options for snack instead of only one item and if there was a TV or music as option. But overall satisfied.

The flight from CLE to JFK was fantasti! Pilots and cre were informative and accommodating.

My flight got delayed for almost 4hrs and then it thankfully went to only 2hrs. Then we were told that there were no space for carry on bags and I had to get it checked... well I counted at least 8 spaces that weren't used and I was one of the few left that actually had one. There was definitely enough space and either the crew can't count or just genuinely are so lazy they don't want to do their jobs correctly and make sure that there ACTUALLY is no space.

Due to an issue with the plane. We waited almost 2 hours to take off. The service reps were great. We had a longer layover but was able to run for it and catch our flight. This also happened on our way out. Maybe the planes need a good look over. The people who work front desk and flight attendants are the best
