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.

So this review is related to some things related more to the airports and higher-level stuff. One issue was that this was the second leg of an international flight for me. It was an American Airlines codeshare with Finnair. American Airlines had alerted Finnair about some additional security measures but did not mention the fact that any liquids purchased at the Duty Free stores en route would NOT be allowed through security at Chicago when transferring to the domestic terminal. Passengers did have the option of placing those liquids in their checked baggage but what if that wasn't an option? Another issue is just related to ORD, it was a zoo. I know that's beyond what this review is about but big airlines like American have some part to play in how the airport operates.
