Anatomy of an Award: Buenos Aires to Honolulu for 25,000 Miles Singapore Miles (Sweet Spot)

Last month, I booked an award from Buenos Aires to Honolulu for 25,000 Singapore miles and about $100 in taxes. The booking illustrates a few topics:

Sweet spots and how to find them
Awards you should book speculatively
Booking awards with foreign programs

The Problem
I have to get to Hawaii for my brother's wedding in February. The main problem is that I don't know where I'll be in February to book the ticket to Hawaii.

Anatomy of an Award: Using Secret United Award Space, Saving $75

Last week I booked myself an award from Chicago to Buenos Aires in United economy for 30,000 United miles + $5.60. This award was very simple, but it illustrated three interesting concepts:

When will last second award space open up?
United's secret extra award space.
The trick to save $75 on last second United award bookings.

Last Second Award Space
I had been searching award space for months from Chicago to Buenos Aires, and there was never any on the inflexible date I wanted to fly.

Anatomy of an Award: Hawaii at the Last Minute for 17,500 Miles

I just booked myself a one way award from Washington-Dulles to Honolulu, Hawaii for 17,500 Singapore miles and $6. There were a few interesting things about the award:

I just booked myself a $1,233 economy flight from Hawaii to Chicago for 17,500 Singapore miles and $5.

You probably already have the miles I used, so you're only a 10 minute phone call away from a trip to Hawaii that costs thousands of miles fewer than it "should."

The basic idea is that you don't want to use United, American Airlines, or Delta miles to fly to Hawaii. You want to use their planes, but you want to book those flights with miles issued by foreign airlines, which for whatever reason, offer far cheaper award prices to

Singapore Airlines Completely Revamping US Route Network: Business Class Award Space on New Flights
