Some potential that I might be in between jobs for a month shortly and looking to fill it with a quick trip.

Thinking starting a DONE4 in CMB.

CMB-HKG-JFK-DFW-ANC-DFW-MIA-LAX-LHR-IST-LHR-SYD (assuming travel in May when the ANC starts)

then hold Australia and the finish in Asia over for 9-12 mths.

What are my chances of getting D-class availability on that many flights so close (ie no more than a month out - first legs within a week of wanting to book)??

Just want to get an idea before I even go to looking at setting up flights.
