Round trip flight to Canada and back to the US was smooth and efficient.

Round trip flight to Canada and back to the US was smooth and efficient.

The agent at check in and at the gate were less than thrilled to be at work. I'm not a fan of Kayak's placement on the plane. I got put in the middle seat and none of my preferences were used.

Spanish speaker flight attendants were incredibly rude. A male flight attendant named Allen, grabbed my bag out of the overhead bin and moved it without my permission. When I asked what he was doing, he informed me that the overhead bins were public space? It would be easy to ignore this comment, as you don’t know the whole story, but the flight attendants were militant and rude. Delta, you can do better!

In ATL they have two sets of departure screens. Follow what is on your airline's departure board - the ATL Airport Authority departure board had completely incorrect details about the gate assignment for my flight, which would have made me miss boarding.

Flight was delayed it was hot while sitting on the plane, one engine was working on the plane until they had to do some jimmy rigging down the runway in order for the other engine to charge up. It was ridiculous

The flight was very good and the staff was very friendly and helpful!

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Very easy to use and convenient, you can perform any action within the same portal

In a world of delays, Delta was on time both ways! Boarding was fast and efficient. Staff was friendly. AND wifi worked.

My business class seat was inoperable and unable to recline for 10 hour flight.
