The meaning is a bit like what Tony Leung Chiu Wai later said to Faye Wong: "If someone gives you such a boarding pass, will you let him get on the plane?" . So this can be seen as an opportunity for women to show their love to the right person, which is equivalent to "I love you, so will you love me?" . It can also be seen as "I will come to you at a certain time and place, will you accept it?"
The only important thing about the "boarding pass" marked with time and place is "Do you want to board the plane?"
I specialize in movies, which is my personal understanding.
