A side situation...

I am calculating my miles and planned my DTW-HKG run so that it JUST over 100K BASED on the fact that I have some 10K miles as missing credit waiting to be posted (BA LHR-Dubai-LHR, and QF HKG-SIN-HKG). If anyone of those failed in some sense i cannot make the 100K and my $7xx run to HK will be ruined....

Am I too risky? Should I do a backup domestic run?
