Frontier flights from Miami to Cancún (MIA - CUN)

The flight was delayed over 2hours which alone was enough to complain about. Once the plane arrived, the one attendant cared more about messing around, talking joking and hugging with the airport staff, rather then getting on the plane to sanitize so we could board the plane. When I found my seat, there was a dirty sanitizer wipe resting in my seat, and there was what looked to be a loogie on my window. The same attendant who was goofing off with the other staff was then talking very condescending to the passenger in the row in front of me because he fell asleep and his mask fell under his nose but still covered his mouth. Next time I will pay more money to have a comfortable flight where my carryon is included.
