Beware SQ also has non-mileage accrual classes.</font>
So far all my SQ flights on M class have been credited to UA, as opposed to the ones in CX not being crdited to AA. Also the very cheap e-tickets booked through SQ's website get me miles (e.g the SG$ 350 Rt SIN-BKK). I will continue pushing my luck with the SQ-UA combo.
