My son is now enrolled at National University of Singapore so for the next 4 years, he'll be flying to/from our home base of San Diego (~8800 miles) perhaps 2 roundtrips/year. Is there a recommended airline and FF program for him (and us, since we may try to visit once a year)? Is it better to do LAX-SIN since LAX is about a 2hr drive away? After college, he has a high likelihood of working in Southeast Asia for a few years too, but I guess that far down the line, FF programs may change quite a bit. Also, the school has arranged one roundtrip to the northeast US on Emirates - is it possible to tie that in with a recommended FF program? I see Emirates is not part of the 3 large airline alliances.
