Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Air travel sucks. It continues to be awful for all airlines. No shame on delta alone.

Delta canceled our flight and we had to scramble to find another airline to get home. Phoenix is not a delta hub so they didn’t have another plane. It would have been a red eye though Salt Lake City. Getting in at 5am. No bueno.

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

The food is terrible. The staff is wonderful. Comfort is good.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

The flight used a B767 with a very old interior from before 2014. The entertainment system did not work at all during the flight despite attempts to reset the system. It was like they flew this route just to be competitive.

Delta made it easy, comfortable and timely. The crew was fantastic.

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

Crew was helpful and cheerful especially when they had no refreshments to work with. The plane was never serviced and had nothing but limited water and coffee onboard. For the price point, a concern of services.

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

It was good. But the gate team made me check my carry on when there was plenty of space for my luggage on the plane. Otherwise our trip was fine.

Bags took over and hour to come out. Delays due to wind caused rebooking.

I bought wifi and most of the flight could not even use it my apps would just spin. I couldn't even listen to music. super frustrating.

Gate was overcrowded. Gate agents performed very well. Flight crew was top notch! Efficient & professional & courteous. Both meals not thermalized well. Dinner main dish was actually cold in the center. Almost inedible. Breakfast sandwich was lukewarm.

RIC Staff was not enough. Elderly passengers had to wait 30 minutes to deplane, so we could board and still had to walk as no chairs were provided. And, passenger in front of my seat assignment rammed seat against my legs entire flight time. Was mildly bruised and left thigh still sore.

Flight was cancelled 3 hrs AFTER etd. Thetefore Missed connection from JFK to New Zealand . No accommodation provided… This cost ne aporox 1000 USD in extra expenses and turned whst should have been a 24 hr trip ftom Boston - New Zealand into a VERY expensive , late 70+ hr nightmare … Complete nonsense!!!

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

Whenever a passenger purchase a ticket his advantage number should automatically to his information. It's not everyone remember the number. You request for your number and American airline agent say they will email it....and they never email anything and you loose your mileage just because you don't remember your number. It should automatically go your information and associate with your email account at all times
