~22,000 miles (GUA/LAX, LAX/NRT, NRT/SIN) r/t is almost MP status. Only a few of these trips in a year would make you a 1K. And besides the miles, you'd be in line for SWUs for the following year. Yes it's a little on the ambitious side if you don't travel much and if this trip is an anomoly. But if it isn't, a future flight in UA/C will always beat the pants off of SQ/Y--no matter how good the food, service, or IFE is.
