I'm on a DONE4 and I'm flying SAP-MIA-SJO-JFK-HKG-BKK-NRT-SIN-MEL-AKL-SYD-LHR-HEL within about a year. I'm OWE on BA and need to get 550TP before august 2013 to retain it until sept 2014.
So I'll probably get those 550TP first (SAP-MIA-SJO-JFK-HKG-BKK-NRT), but any suggestions which FF program to use for the rest of the trip (NRT-SIN-MEL-AKL-SYD-LHR-HEL)? In addition to those flights, I'll most probably fly MH (if in OW at the time), CX and BA otherwise also within a year. Maybe also AA one or two flights.
