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

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

Great - This was the last flight before hurricane closures and did a quick turnaround to get the plane heading north. Much appreciated.

I liked the screens in the seat headrest with movies to watch. I didn’t like being forced to check my carryon bag and being told there wasn’t room for my bag - when there were 5 bins sitting empty on takeoff. I didn’t like the “I don’t give a fig” attitude of the flight attendants and the delta gate attendants when I asked why they decided to put me out. They gave me a 1800 number to call but I can’t get a live person on the phone. Customer service is non existent. My business must not be that important to them.

It was not in Delta's control, but when we landed, we ended up parking at the wrong gate, and so everyone was already ready to deplane and had their carryon bags, ready to leave. But we had to sit down and move to the proper gate. This process took over 30 minutes. Again, not Delta's fault - more so on the staff at JFK

It’s was good. There’s so much room for improvement though. Since the plane was small, there was no entertainment but for years now, the most jarring aspect of travel is the lack of tasty snacks.

Love delta but the delays and long waits for updates was just too much this time.

Flight for canceled. Horrible experience.. had to rent a car to drive myself up here.

If I can, I always fly Delta. I’ve found their service to always be reliable and pleasant.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

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.

The crew was outstanding. And the food was surprisingly good. The chicken and the pasta dish were both delicious and I was supposed with a pizza twist near Landing. We hit a lot of turbulence and the crew was calm and kind. Loved the TV in screen. Tons of new releases.

ANA was great. United was horrible. They bumped us from economy plus to economy and were supposed to contact us for a refund but no luck. We booked the seats 9 months in advance.

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

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward into a very uncomfortable position and it is not removable.

Boarding in Paris was a nightmare for us. Why passengers have to get checked luggage tickets and then to go to counter to get luggage weight and send to the conveyor? We counted 14 security and airline checks before getting in the plane. We will never again use United or travel to France, neither stop by IAD airport.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

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

Just about made it for the next flight. They need to put in longer layovers if they know they close the gate 10 min before they take off. I will never do a layover for less than 90 minutes

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

Overall boarding and debarking is a joke. I dont even bring luggage anymore on trips because you can never allow them to be place then in the overhead bin or you have to pay or you check them which is even worse having to wait for your luggage on the tarmac.

It was on time, which is always a good thing. There wasn’t any food hence my okay rating.

Excellent accommodating crew at gate and on board. Baggage claim and gate checking were flawless.

Best flight by a pilot I’ve ever been on as a 62 year old

After multiple delays (I lost count), the flight was canceled due to a "maintenance issue". So instead of a direct flight arriving at 5:00, I had to take a flight connecting through Chicago. That flight was also delayed, partially because the plane from the cancelled flight hadnt been removed from the gate and there was nowhere for the other plane to park. (Did nobody think this might be an issue during the hours after that flight was canceled?) The connecting flight out of Chicago was delayed as well. I didn't arrive until 12:30am the next morning. I should have just cancelled the trip. It wasn't worth the hassle and stress.

Perfect flight. Efficient boarding, on time take off and early arrival. Generally smooth flight.

Terrible. I didn’t fly and I had an important meeting the next day.

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.

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.

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! 😂

Smooth enough, delay-free and safe. All went as expected,

Not acceptable having both flights delayed and not real reason for .. plus paid for luggage and getting my bag ripped out .. very disappointed.

the seats are the hardest I've ever felt; narrower and less leg space and I am small. I could have bid on a comfier seat but the price would have ended up closer to an economy plus seat on a more reliable airline. Only used this airline because of the timing and non-stop. I was afraid from the get-go I wouldn't get there. Apparently, I was lucky

Seamless boarding process, flight was early, crew and passengers nice. Crew was professional as well. Seats are super thing but reasonably comfortable for a 2-3 hrs flight. No on board entertainment, except maybe for paid internet. No water, no snacks. I feel all airlines should offer free water. I didn’t care paying for it, however water is free everywhere in the US and it almost like a basic human right in a civilized society.

They lost my luggage on a direct non-stop flight.

The flight landed with a delay and we had to wait almost an hour to be off boarded. So typical of spirit.

Staying with Dallas 4 hour stay ...it's was torture sorry. .. about to say that
