I booked online a flight for my aunt last month. She is scheduled to fly on March 16, 2011 from Manila to New York. Her China Southern Airlines ticket number is 7847951573754 with confirmation code NYJWKH. I read in the itinerary that she has to confirm with your airline at least 72 hours before her departure. Inasmuch that she is in the Philippines, what is the phone number that she has to call?

Hoping to hear from you soonest.
