This is the sixteenth post in a monthlong series that started here. Each post will take about two minutes to read and may include an action item that takes the reader another two minutes to complete. I am writing this for an audience of people who know nothing about frequent flyer miles, and my goal is that by the end, you know enough to fly for free anywhere you want to go.

I've covered how to earn miles and the redemption options for miles.

Let me clear up one of the most common types of questions I get from beginners.

There is no transitive property of miles.

Just because Airline A partners with Airline B and Airline B partners with Airline C does NOT mean Airlines A and C are partners.

For instance, in yesterday's post Fully Flat Business Class to Europe for 25,000 Miles, I wrote:
I searched award space on Aer Lingus' routes from Chicago, Boston, and New York to Dublin for one passenger next April through July.

I searched on united.com.

Loyal reader Drew sent along an amazing targeted offer he received to continue spending on his US Airways® Premier World MasterCard®.

If he spends $500 per month on his card in August, September, and October, he'll get 15,000 bonus miles!

That means for a total of $1,500 in spending, he will earn 16,500 miles, which is 11 US Airways miles per dollar!

The email came to Drew with the subject "Earn 15,000 miles with your card!" Check your email for a similar offer if you have a US Airways® Premier World MasterCard®.

Most of us

There is excellent award space in Japan Airlines First Class between San Francisco and Tokyo for most of the next 11 months.

Three months ago I wrote that US Airways would be losing five of its Star Alliance partners over the course of 2014. The final two of those five bite the dust this Thursday!

July 31, 2014 is the last day to use US Airways miles to book Turkish Airlines and Singapore Airlines flights.

Turkish has seven routes from the United States to Istanbul

Note that the flights need only be booked by July 31. You can book US Airways awards up to about 335 days in advance.

US Airways charges only 60,000 miles roundtrip in economy to North Asia.

US Airways miles can get you to the Middle East and Indian Subcontinent on Qatar Airways flights in Business Class.

American Airlines and US Airways are currently offering huge bonuses on transfers from SPG Starpoints.

Until July 31, 2014, you can transfer 20,000 SPG Starpoints to 30,000 US Airways Dividend miles.

This promotion is identical to the current promotion to transfer 20,000 Starpoints to 30,000 American Airlines miles, which makes sense since US Airways and American Airlines have legally merged.

Yesterday I said about the American Airlines promotion: "it's July 2nd, and I think we can probably declare this the best miles deal July will see!" Of course, such a statement was disproved in less than a day because I consider the US Airways promotion slightly better.

How many Starpoints

US Airways Dividend Miles are extremely valuable for award flights to Europe because they can be redeemed for awards on all oneworld airlines as well as a number of Star Alliance airlines.

All together, that's nine airlines you can use to cross the Atlantic, and you can even add in a stopover or an open jaw for free.
