From checking to boarding, it was a seamless experience. The service agents were so helpful. The flight crew was so pleasant.

Delta has too many delays now days. It is 1:06 am now. I was supposed to land in Norfolk at 10:30 pm. I got re-booked through Detroit and I’m still in Detroit. I hope to be landed in Norfolk by 3am. I’ve been in airports for 12 hours as of right now. There is a weather delay now but most delays lately have been maintenance.

This is the first time I've been disappointed with Delta. I was called by Delta to see if I would volunteer to change flights since my original flight home was overbooked. I accepted. The modified booking only provided me a 35 minute layover - when you subtract the fact that boarding closes for a flight 15 minutes early, that gave me 20 minutes to run for one end of the airport to the other. I barely made it. On the 2.5 hour flight to Tampa, the crew repeatedly let us know over the intercom that they cannot serve drinks or snacks due to safety/turbulence. I would have accepted this reason if they did not CONTINUALLY SERVE DRINKS AND COOKED FOOD to First class. If safety is the excuse then the entire plane should be strapped in for safety. On top of this the air conditioning vents were not working correctly and the plane was uncomfortably warm. I love Delta and am a loyal Delta traveler, and I have never had an experience like this. I don't know if there's a disconnect between availability among third-party sites like KAYAK and the airlines or what, but when overbooking causes issues like this for travelers it should be reviewed and changes to the booking process should be made. I blame BOTH KAYAK and Delta for this terrible experience.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

My flight was canceled after being rescheduled for four days canceling my trip. Kayak and everyone affiliated with it I.e the airlines, and just fly have been excruciating to deal with. My trip to visit family had to be canceled as there was no way to make it. I am furious at all of you.

They delayed our flight because of bad weather in NY which was completely understandable. Then they cancelled our flight and a later flight that evening. The earliest we could fly was the next morning. We ended up buying last minute tickets on another airline and made it home slightly delayed but safely that evening. Delta kept saying it was weather related but if that was the case how did we make it back on another airline? The weather in NY was cloudy but not bad.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

I always fly with Delta. My friends tell me their horror stories of flying with other airlines. I just smile and say, “You should fly Delta”

The plane smelled like a sewer. Multiple passengers complained. It’s a safety and quality issue to clean these planes.

We were delayed 2 hours leaving STL. I had 20 mins from when we landed in SLC terminal A to make it to SLC terminal B. I had to actually run! thankfully I made my flight but 3/4 legs were delayed to some capacity.
