What time is the man’s flight? Who is asked to call back?

M: Sue, could you change my flight reservation for me? I’ve got an appointment in the morning so I won’t be able to leave until after midday.
W: Yes, of course. What about the 1:15 flight? You’ll get in at 3:30, so you’ll be in time for the evening meeting.
M: Thanks. That sounds great.

M: Peterson and Taylor. Can I help you?
W: Yes, this is Isabel Hawkins from R&D. Can I speak to Dorothy Borrow, please?
M: I am afraid she is not in at the moment. I am the secretary. Can I take a message for you?
W: Yeah, ask her to call me back this afternoon. My number is 7787607. Thank you.
M: You are welcome.
