the issue isnt whether you can do it. the 180,000 gives you enough miles to do it.

the question becomes how to do it.

the singapore airlines flight is the ideal way to do it. It's the fastest and best service and with a bonus that you can leave at 11 p.m. at night.

but if that doesn't work, there are multiple ways to do it, flying to asia from ny (thru thai air), from chicago, la or sfo to nrt, then to singapore. but you really can't check any of this online. it has to be done thru an agent because you might end up getting some combination like singapore there and thai back or united one way or some such
