Just booked ORD-HKG for April travel, business class on Cathay Pacific.
Online was showing $7303.51, booked via IAP for $5911.33 (+$39 booking fee) per ticket for a savings of $1,353.18 ($2706 total for the two tickets)!
Booked online using the chat feature. Took no more than 15 mins from start to finish. Very happy with the entire process and the savings of course.
