Everything was great. Great service, excellent communication, and early arrival

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.

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Attendants zipped through cabin so fast hardly anyone got the water they told us we could have in the short flight. Nothing else was offered.

Sucks ! All three flights I was on this trip were delayed.

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.

Flight areas delayed 3 hours , train in the airport didn’t work

The flight was on time and everything went very smoothly.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

We were offered Flight Change due to overbooking. We accepted and chose an earlier flight. We went to Rebooking center to make the change but agent told us no changes permitted on our Basic ticket. AA should not have made the offer to change our flight.

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

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.

I’ve now flown Spirit a few times and while the general perception of Spirit I feel is poor, I’ve had a great experience each time. They do charge extra for everything but you should know that going in

The people were wonderful, but I hated the way they over charged for luggage, especially for stops which were charged the same as starting point to final destination.

Very mean staff. No entertainment.. No WiFi, a baby cried for over 3 hours no staff offer to assist. My son $500 computer screen got damaged under the plane due to force check in of my bag. TERRIBLE EXPERIENCE!

Nothing I liked. Seats uncomfortable child behind kicking my seat entire flight. Delayed. Couldn't get free glass of water

I did not fly Spirit. Connie used my email while booking her flight. I do not know Connie. It's fraud!!!

Horrible. Take off was delayed by an hour. They were letting people board d the plane right before takeoff. I was delayed an hour when I arrived and late for my meeting. Spirit is NEVER on time.

My other half doesn't have his luggage and I made a mistake by getting 3 check in bags instead of 2 and I'm going through changes to get credit for the one I didn't use. There giving me the run around!

The boarding was quick and orderly, but the seating is tight and not in a good way.

Absolutely the MOST uncomfortable seat I've EVER had on ANY airline. It should be a criminal act (cruel & unusual punishment). NEVER AGAIN will I travel your airline.

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.
