I originally wrote this series in 2012.  As it has turned out to be quite popular, I am in the process of updating it to reflect current information for 2016.

Singapore Airlines is altering its routes to the United States in October 2016. Currently, Singapore flies from four American cities to Singapore with stops along the way in Europe and Asia.

San Francisco to Seoul (ICN) to Singapore
San Francisco to Hong Kong to Singapore
Los Angeles to Tokyo (NRT) to Singapore
Houston to Moscow (DME) to Singapore
New York (JFK) to Frankfurt to Singapore

Singapore is making several changes though.

Let’s talk about transferring Membership Rewards to airline partners for redeeming on domestic awards. This is part three in a series that will allow you to master redeeming awards within the United States, no matter what kind of points or miles you might have.

For those of you that have already read the first and second post in this series, you will notice repeat information at points in this post (as well as the rest of them to follow) because some of the airline partners overlap between transferrable points programs.

I've been hopping around Europe for the last few months with flight that I've booked a variety of ways:

Barcelona, Spain to Leipzig, Germany (cash, Vueling)
Prague, Czech Republic to Belgrade, Serbia (Etihad Guest miles, Air Serbia, Anatomy of an Award)
Belgrade to Tivat, Montenegro (cash, Air Serbia)
Sarajevo, Bosnia to Zagreb, Croatia (cash, Croatia Airlines)

Now I have two more flights coming up from Zagreb to Spain and back for a quick trip.

Perhaps because it can seem daunting to precisely calculate the value of a mile, I had seen no systematic attempts to do so mathematically when I first started writing this blog.
