Poor|Oct 2021

There were complications with my flights boarding in spokane and my secondary flight was changed without my consent to one that boarded at the same time as my first flight let me out on the opposite side of the massivr layover airport. It was only because an employee saw my struggle and confusion and hooked me up with a ride that I even made the flight dispite delta's best efforts. My TV's headphone jack on my first flight was also busted which sucked to find out after buying headphones on the flight. About halfway through the flight one of the attendants moved me to a seat with a working TV. Long story short Delta as an airline was terrible but their employees did their best to help me with what limited options they had to work with.

Okay|Apr 2022

No entertainment, five hour flight and choice of pretzels or a cookie. Still a place to put your cigarette in the restroom on board. How old is the plane?

The staff was the highlight. Only thing that could have been better was the temperature on the flight from Hawaii to Seattle. The plane was too cold to get comfortable

Poor|Oct 2021

I never took this flight and was never able to cancel it in Kayak’s system! I will never book through Kayak again. The flight was probably fine. Next time I will only book with the airline directly. I would caution anyone else to do the same.
