Sat in the plane at the gate in SLC for 2+ hours before take off, getting me home nearly 3 hours later than planned.

Sat in the plane at the gate in SLC for 2+ hours before take off, getting me home nearly 3 hours later than planned.

I was impressed with how quickly the baggage transfers were made.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

For some reason, there was very little volume on the cabin announcements. You could not hear what the pilot or crew were saying.

Carmen was an absolute delight on the flight staff! Everyone was lovely and made it a very pleasant flight.

Flight was delayed at airport with large backlog and WiFi was spotty

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

Nothing unusual. It was fine. I hate having to pay extra for my seat.

Didn’t make the flight. My connecting flight was an hour late and I missed the flight. You rerouted me thru Atlanta and I arrived in Rome over 10 hour after my original Rome arrival time. You also left my luggage in Atlanta and it took you three day to get my bag to meI spent 4 days in the same cloths, I had packed my prescriptions in the lost bag and went 3 days withoutMy heart meds.
