5 member crew including 1 deadhead. Not sure if he was working but wonder about some of the others. Liquid dripping on passengers and they offered paper towels. A young man who seemed very agitated collapsed into the aisle just before landing and no one moved. Not even deadhead just in front of him. I think he had been overserved and they tried to forget that. Very bumpy landing. Flight attendant offered fresh air, not barf bags. Better than most Frontier flights but not saying much. Won't fly again.

Confusing to book and check in. You book with Alaska and fly on American Eagle. Be sure to check in with American Airlines and use their flight numbers and confirmation numbers - NOT the Alaska Airlines information.
