This movie came out when I was 8. When I was 8, I was not familiar with airline tickets in any way. So no, I didn’t pick up on the red ticket jacket mixed in with the red napkins in a two second shot. I was focused on the violent physical comedy to come! Also, major plot hole - if that was his ticket, how did they count the correct number of tickets at the airport? If I had picked up on the ticket in the trash, I’d also assume they’d found it when she counts the tickets and isn’t like ‘weird, missing one’.
