I wish I had read this. I booked award ticket, F, from ORD-HKG-ORD on Jan-29.
I used two AMEX cards to pay. One for some miles to top off what was needed (to be charged in USD), and the other to pay for the taxes (to be charged in HKD). I used two to avoid a foreign transaction fee, while maximizing the 3x point bonus from AMEX for air travel! :-)
I check the website today and found it had not been ticketed. Some warning about "Ticket by Jan 28 or it will be cancelled!" Of course, panicked and called MPC. Told it was a problem with two charge cards. Huh? If this was going to be a problem, then why did they accept two in the first place? And why didn't anyone contact me? Were they going to just let the ticket cancel?
Anyway, I pushed hard, not wanting to risk a cancellation. A few hours later got an email confirmation of the eticket. It was preceded by email from AMX telling me my card had been charged in HKD, instead of the USD they promised!
Anyway... probably a $50 ding in FOEX charges.
The ticket shows surcharges of $1338HKD. From reading the above posts, it sounds like YR is the fuel surcharge? It is 712HKD. So if I had waited one more day, I would've saved a little on the taxes/surcharges?
Sigh. Oh well....
