In terms of the FF Status, I was wrong, you will be close to getting Senator with a RTW 39k on C Class.

Here is the math,
If you live in Canada/US, you can have the 25% status bonus kick in after 35,000 status miles (or at 17,500 flying miles * 2 for C class).

So,
17,500 * 2 = 35,000 status miles
21,500 * 2.5 = 53,750 "

Total = 88,750 status miles
