Delta is a premier airline so my expectations are most always met.

Everything was good except when we're on a 6 hour flight at dinner time and all they offer as part of the fare are little bags of junk food, it's disappointing. Bring back food service without an added price.

Left on time and arrived early this extending our 31 minute transfer. Bags made it also!

I actually received a notification from kayak on email but not one by text from Delta when my departure gait changed and I almost missed my flight

New boarding doesn't make sense. Filling front first is slow.

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

The flight was so late that I had to change connecting flights, turning a five-hour trip into a fourteen-hour nightmare.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

The fight was about 2 1/2 hours delayed, but that was weather related. The flight was also overbooked. But we were in Comfort plus so the flight was fine for us.

It was pretty good I was worried with the short Layover that I might not catch my connection but the gate was there
