What does the woman imply?

M: Would you like to go with me to the airport to pick up Frank?
W: I’d like to, but I have class till 2:00. And I know Frank’s decided to take the early flight.

W: Hello, Mr. Smith. This is Mary. I’m sorry to tell you that Dr. Brown has to change your appointment to tomorrow at the same time. His flight is late. He is still in New York now.
M: Oh, well, thank you for calling. I’ll see him in his office then.
