Flight Ticket Booking

I called the travel agency that almost all my other Ross 08 students choose to book the tickets from my country to Detroit. Five days past, I called up them again and got the feedback of "not getting the tickets yet". After August 10th, there are flocks of people flooding into US for study or for business. I seems that it will be very difficult to get the tickets. Bless me God. Come on, my ticket lady, do not let me down.
