I would fly again the whole experience was great. The only feed back I can give that they don't do that American Airlines does is the crew there is more humorous with boarding and thank their passengers. It makes it more fun to fly with them. I would however fly Delta again.

Horrible. This was not first class. This was a connecting flight whi h was late. My original flight never came. I hated the fact that delta gave me a connecting flight from New York to Orlando Florida. No meals and the television screens were not working. There wasn't even any power to charge your phones. This is NOT FIRST CLASS DELTA!!! Do better next time!

They did a fine job. Can't wait to use Delta in the future.

Seat back monitors and outlets were dead and not working.

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

public website still broken for years randomly blocking browsers with privacy options active after loading a page maybe once. check-in on laptop was almost impossible but eventually randomly worked. had to print pass at airport since couldn't get back in to load digital pass on mobile firefox or chrome. red eye flight so smooth onboarding, plenty of room to spread out, easy offboarding. onboard wifi instructions mention vpn can cause problems connecting but fails to also mention private dns. no printed or built in menu list, seems weird to require personal device to point at qr code link for menu which does not even allow direct ordering. people with health condition risk related dietary restrictions trying to avoid for example cholesterol and sugar are left guessing what they can order either way without nutritional info highlights (cranberry juice was minute maid cocktail with as much suger as typical can of soda). tap to pay wasn't working and always seems sketchy to manually enter card info. good movie variety, so limited tv was okay.

Boarding super slow with people allowed to linger in aisles

There were choices for the snacks. Good choices and tasty lunch and breakfast as well.

First time travel in economy and the worst experience I ever had ! Shame on paying 600 dollars to be in a tuna can ! Service was terrible no even water no even class no even matters your flight attendants were lazy and sloppy very bad experience! After all these years traveling in first and once I try this cause I need to go to a destination for an emergency wow shame on you !

Flight was cancelled had to move to another gate late again no internet paid for the month and never can use it waste of money

Flight delayed over an over all day until it cancelled at 1:30am. Would not repeatedly delay that late. Offer hotel rooms and rebook early. Very difficult for families with small children

It was a good flight. Of course it was full, but it went well.

We sat on the plane for 1 hour because the airline was short handed could not be unloading.

We sat on runway for an 1 hour because they were short handed at key west airport was not fun

We are gluten free, there were not any available complimentary gluten free options.

Flight delayed 3 times. We were directed to go to a gate across from our gate. The plane wasn't there yet so we had to wait for it to arrive, then deplane everyone and then wait again for the plane to be cleaned. After 45 minuites we were allowed on the plane. The first plane had mechanical issues. The 2nd plane must have had bathroom issues because we did not have any food service whatsoever. No snack or beverage. That made for a long time not to have anything considering that we had just made it to the original gate and we had no time to stop to get food or a drink. Then we didn't want to leave the gate to get food because we wouldn't know how much longer the delay would be. Then the next gate change. Had we been told that the total time would have been aprox 45 min later we would have left to get food and a beverage. We had to wait again for the okay to the pilot to take off so we were on the runway for another 20 min. Overall, we were delayed over 2 hours which felt like 4 hours.

Lots of weather delays that were poorly communicated and managed. I get there are weather delays but they didn’t make it clear what was happening or comfortable on the plane

Me and my husband experienced very bad in American Airlines. We missed our flight going to Doha. The American Airlines was delayed we arrived already 10:27pm. Supposed to be 9:40 pm. So what they did they rebooked our flight and they gave us a hotel. When we arrived at the hotel the front desk said it was fully booked already. Oh my gosh! I said why did you accept the booking if it's fully booked. The guy said that's American Airlines they just book even it's already full. That's 2am already, we have nothing to do so, we decided to go another hotel. We pay the room, food and taxi. Pls give an action on this matter. Refund our expenses and give us more compensation. Not only our room, food, taxi but also our efforts, tiredness looking for a room that can accommodate us.

Horrible. Flight was delayed and very bumpy. I was super unhappy

If you take this airline, they WILL change the flight time, and make you miss your connection. It has happened every time I used it. It's so unreliable that I think it shouldn't be offered on Kayak. You will regret it!

In addition to the fact that Silver changed the flight time several days before the trip without offering any choices , I was sick with Covid and unable to go on the trip. I tried to ask Silver for a credit for a flight when I’d recooperated but they don’t do credits, even for illness. I will Never fly on Silver again

I canceled due to a 7 hour delay. Was forced to book another airline last minute , very expensive. Silver Aorways sucks

I spent hours with orbitz to get my tsa # on my ticket. They didn’t have a place to enter. I will never use orbitz again. No customer service. A number in which u press offered options and the message replays instead of getting customer to that area. Silver did not make the promised call back. Finally someone responded to my email and took care of it after I lost hours of my vacation arranging this. Staff on flight barked orders.

Our pilot and flight attendant, Desiree, were great. I always fly this route and this crew was better than most.

The worst flight ever; 1st and last flying to this airlines

Easy boarding and deplaning. Short flight. Water was given but that was it.

Flight was delayed a bit since booking but otherwise everything was very good.

While this is a VERY SMALL plane; take-off to landing was fine. It's the constant departure time changes that wore me out and I'll try to never use this inconsistent airway again. Four delays in one day. Done!!!!!!

This has been, by far, my worst experience with an airline company. I had a reservation for a Tuesday at 8:30 pm departure from Gainesville, FL (1.5 hours - direct flight) I received an email on Monday that my flight had been changed to Monday at night to depart from Jacksonville, FL (and it was an 11 .5 hours flight ). There was no way I would have had the time to gather my things, drive 1.5 hours to the Jacksonville airport, and make it on time to board the plane. Besides, I had a full day of work on Tuesday. The only good thing I xan say about Silver airlines is that they did give me a refund, but I had to wait about 4 hours for a call back
