When will Ms. Austin leave for her trip?

W:I’m calling to confirm my flight to New York this Saturday. My name is Jane Austin, and my flight number is K701.
M:Yes, Ms. Austin. Your name is here in our computer. I’d like to remind you to please come to the airport two hours before your departure time to get your seating arrangements.
W:Thank you. And by the way, could you tell me once again how long my flight will be?
M:The total number of hours is 16 hours because you have a two-hour stopover at Los Angels International Airport.
