This was a nicer flight - not fully booked and so we were able to spread out.

We had a nice flight. Boarding was easy, our seats were comfortable and the on board service was pleasant.

Planes are aged. The wifi is unreliable and on many fights, no-existent. The flight attendants were very good.

I had a wonderful flight, but the only thing that annoyed me was how crowded TSA was. I still believe airports and all planes work together to bunch everyone together to drive up cost.

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.

I sat in comfort plus. It was fine. Seats were comfortable. I got drinks and snacks.

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.

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

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.

I appreciated friendly service from check-in, to boarding, to in-flight amenities! Attendants were accommodating and helpful. Thank you! Elaine

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

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Had a crying baby and a toddler behind me so it was difficult to get comfortable. Searing was tight even for a relatively small person like myself (5’8” 155). Fast flight but arrived so early the gate assigned was still occupied by another plane so we had to wait for about 20-25 minutes to get reassigned to a new gate and get over there.

Best part: It’s operated by All Nippon Airways. It’s quite literally comfortable, reliable and respected from boarding to landing each and every time. It’s perfection without extremity in lavishness — it’s how flying should always be!

The flight attendants were unhelpful. It was a packed flight, and usually a flight attendant would help find a spot in the bin for your carry on or shift things around. Neither made any effort to do so. Also, I had to then check my bag. I was told it would be on the carousel in YYZ, but it came up on the jetway. So lucky I saw others standing around for their bags. I would have walked straight past this and on to the carousel. They could have at least told me that they had given me wrong information. Very unsatisfactory.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

The check-in process is not the best They should have agents in site to help with any problem especially a rebook. Why does one have to get on the phone when there were at least 8 agents around that could have help?! Flying is stressful as it is and having someone willing to do their customer service will ease some of the stress.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

Seats are smaller and harder than other airlines we have travels with. Food was edible but no good. The sandwich was the only thing I would eat again. They did have a lot of movies to watch.

boarding was uneventful. Snack was pathetic. A tiny fruit bar. Entertainment was limited to just select movies on your own tablet or phone. No live TV. I recently flew Jetblue and they had unlimited snacks and live satellite TV the entire flight. My seat was an exit seat, 20A. It was super uncomfortable. It felt cramped and the middle seat was taken up by a large woman who pushed into my shoulder and arm. Horrible flight.

I liked that the flight to Kosice was on time, the service was excellent and we arrived to Vienna early. The only thing I did not like, is that I had to pay for my suitcase $75. Bummer

Finding the gate was very confusing. Our boarding pass listed one gate and the staff verbally told us a different gate.

Plenty of overhead space but forced to check my carry-ons both legs

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

It was as expected for such a short flight. No complaints

The departing flight from Newark to Charlotte was fine. It was the returning flight from Charlotte to Newark that was awful. We had scheduled an 8:35pm return flight time. We got delayed TEN times all the way to 5am in the morning! We were told over 4 different excuses as to why the flight kept getting delayed. First it was the flight crew needed to rest, then it was something technical with the plane, then it was something with air traffic control, and finally it was because they couldn’t find a captain and had to wait until the morning so the captain could get some rest. It was terrible sleeping overnight in the airport. They offered a $12 meal voucher. That was it! And the only place open in the middle of the night was Dunkin’ Donuts who didn’t even accept the voucher. They should have cancelled the flight much earlier on in the evening instead of just stringing us along hour by hour with more delays. Not professional and unacceptable. There was no refund for inconvenience. I probably will not be flying American Airlines again.

This leg they tried and did well with what they had to work from.

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight was as good as it gets when flying. On time departure and arrival plus no lost luggage.

My boarding pass wouldn't pull up in the app very easily and had to really dig through my email. That caused a delay in TSA..

Packed commercial flight was as comfortable as can be expected

Boarding was slow the scanner broke mid through boarding and they had to manually do it

Average, boarding was ok, the eye scanner broken mid way through boarding they ahd to do it manually. Did not eat any food, Not even water was offered for free.

Boarding attendant was rude. Crew on the plan were more interested in talking amongst themselves and did not ask parentage if they needed anything or even walk down the isles.

Flight was ok with exception of the multiple delays. As with all Spirit flights, the sights are extremely uncomfortable and lack leg space. However, the price savings is the plus.

WiFi didn’t work despite paying for it. Crew was nice.

I upgraded my ticket at the ticket counter and was not informed of the huge bottleneck at TSA pre check. It took me over an hour to get through the line at this small airport and although I ran to the gate and reached it prior to scheduled departure, it had already pushed pack. I missed the flight. Spirit rebooked me on a flight to Orlando that evening, which would require me to then rent a car and drive to FLL. For scheduling reasons, I determined it be would better to rent a car in Pensacola and drive it to my destination in FLL. Spirit called me that evening and asked me if I was going to board the plane. I explained no, for scheduling reasons. The person apologized and said I would receive a refund, but I have not heard back. Certainly, I ought to be refunded the upgrade I paid for at the counter.

The staff from LAX to New Orleans were rude but the staff from New Orleans to LAX were nice!

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!!
