Just booked 3 tickets in Business on Singapore Airlines.
LAX - SIN - RGN with a stopover in SIN
Open Jaw
REP - SIN - LAX
176K SQ miles, and $235 YQ / each
I had to call in as you can't book open jaws online and the phone booking fee was waived.
They made it pretty easy to book all 3 tickets on the same call pulling the miles from each of our accounts.
The whole call took 12 minutes.
