Eugene, Aug 2026

Pushing back flight and ultimately cancelling it after multiple changes and hours of delays. Comm were terrible as to what was going on and what options were available.

4.0 Mediocre

Norman, Aug 2026

Even though we arrived early and checked in, for some unexplained reason, our bags were removed from the plane and put on the next flight. It took over 12 hours after arriving to get our bags.

2.0 Poor

Jim, Aug 2026

WiFi was not working. Flight was delayed in Paris as luggage needed to be removed from the plane that didn’t match a passenger on board. Upon arrival in Detroit the plane couldn’t get to the gate as the pilot turned onto a runway with construction in progress . We waited to be towed back onto the runway. We were almost an hour late causing many passengers to miss their connecting flights.

The morning calzone was less than impressive and we ended up with heartburn

10.0 Wonderful

Patricia Lynn, Aug 2026

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

8.0 Very good

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

8.0 Very good

Christopher, Aug 2026

I am ina wheelchair and the gate agent knew exactly what to do when boarding just the the one of the flight attendants

4.0 Mediocre

Stacey, Aug 2026

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.
