4.0 Mediocre
There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.
M
2.0 Poor
Terrible. so many delays with no communication
J
2.0 Poor
Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.
X
4.0 Mediocre
Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.
M
2.0 Poor
Although I know the Airlines cannot control the situation when there’s a ground stoppage, it would’ve been nicer if we would have had more up-to-date information clarity around the delays. Additionally, I think the delays also took a toll on the Cabin crew, particularly the lead flight attendant in first class. She was not very friendly when we boarded the plane for many of the passengers. Number one she refused to hang a garment bag in the front closet for a first class passenger, she was unwilling to dispose of an empty bottle in the trash as I was boarding (despite drinking a bottle of water herself and needing to disregard), and she was very combative with a passenger, who needed to access something from his bag that was Gate checked. Frankly, it was really unfortunate as I’ve never seen a flight attendant behave that way directly to the passengers, particularly when none of us had done anything wrong.
D
10.0 Wonderful
overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.
L
8.0 Very good
The internet was spotty and I was unable to watch any movies on my iPad; the flight was fine otherwise
R
6.0 Okay
While it wasn't the crew's fault, it was a frustrating flight. We sat on the runway for 2+ hours. Both of the flight attendants were excellent and did a great job checking on the passengers. The pilot did keep us informed about the wait. I appreciate the crew apologizing for LaGuardia airport's backup.
