I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

I have Precheck. Flew HPN to DEN and return this past weekend. Delta didn't attach my Precheck number to this trip. So it was waiting in general line especially in Denver. Unavailable.

worst flight ever from Delta, it got delayed and kept on delaying..

Terrible. Four hour delay because Delta could not find crew to man the aircraft. Terrible communication. Terrible insight into the delays. One of the worst flight experiences I’ve had.

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

Flights on time. .Ride was as comfortable as can be expected in steerage. Luggage arrived at destination. Attendants were fairly friendly.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

Boarding was great. The flight landed early. It took the crew over an hour and a half to bring out drinks. I paid to upgrade my seat to Comfort+ only to be near a crying/screaming baby who was seldom quiet. Noise-cancelling earbuds didn’t even help. Waste of money to upgrade.

This flight was supposed to land at 10:55 pm on January 14th. Instead, it landed at 3:20 am on Monday, January 15th, resulting in a completely lost day due to not going to bed until 5:00 am.

We finally got on a flight about 10:45 that was to leave at 7:30. Bah humbug!

I needed internet for critical matters and it never worked.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Was great in general, try to respect time and excuses when slight changes have been made, appreciated!

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

They cancelled our connecting flight resulting in another layover reaching our final destination 8 hours later than scheduled.

On-time arrivals and departures. Crew helpful and friendly. Yet everything costs extra: seat selection, food, even airphones!

Second time with Saga Premium, everything was fab, but the entertainment centre on both my flights didn't work, plus the seat on the NY to Rek flight (Airbus) was so solid and so uncomfortable. The 737Max flight's seat was much, much better.

The staff was kind and helpful. There was no food, and you needed to bring your own earphones to use the entertainment, which I didn’t know.

Delays at check-in, seemed like they were short ground staff at the time and some passengers needed extra processing.

Problems checking in both on the laptop and on the app. No free seating available at check-in as advertised - must pay for EVERY seat between $23 and $75. No way to cancel seat choice. App menus and site menus are not responsive, and some items are impossible to find. Crew and mobile assistance are friendly and helpful.

Food - Non-Existent. You pay for everything. It is strictly Pay-to-Play!
