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.

Recently, I posted about how we can get amazing value from the fact that the Singapore Airlines KrisFlyer program considers Hawaii to be part of the same region as Central America. We can also use this sweet spot for great value on travel to South America too!

On the Singapore Airline's award chart, it costs fewer miles to fly between Hawaii and South America, routing through the continental United States, than it does to fly directly between the continental United States and South America.

Adding Honolulu to Houston lowers the price of Houston to Buenos Aires

I've collected and redeemed millions of frequent flyer miles over the last three years. By the end of 2014, I will have visited over 50 countries, often flying in First Class.

Singapore Airlines' award chart has an amazing sweet spot: Hawaii and Central America are in the same region!

Flights "within" the Hawaii/Central America region are only 35,000 Singapore miles roundtrip in economy and 60,000 miles roundtrip in business class.

That 35,000-Singapore-miles award would cost 80,000 United miles.

Update: Super reader Dave made a map of the locations of the Category 9 and 10 properties for visual learners.

Super reader Jeremy has created the most valuable spreadsheet imaginable for the Hilton HHonors program that you can download for free here.

The spreadsheet lists:

all 34 Category 1 hotels
all 131 Category 2 hotels
all 46 Category 9 hotels
all 10 Category 10 hotels

For each hotel, the name, location, and a link to its Trip Advisor reviews are listed.

Jeremy took the information from Hilton's PDF of all its hotels' categories and made it much more useful and

My friend has big trip aspirations for this summer, but nothing booked.

Approx July 12: Boston to France, Italy, or Spain
July 13/14 to 24/25: work on a vineyard in France, Italy, or Spain
July 25: vineyard location to Croatia
July 26 to August 2: Yacht Week
August 2: Croatia to Greece
August 10/11: Greece to Boston
August 22: Boston to Colombia
August 31: Colombia to Costa Rica
Sept ~7/8: Costa Rica to San Francisco

She emailed me for my suggestions.

On February 1, United miles became much less valuable for premium cabin flights.

Not only did all first class awards outside of the western hemisphere go way up in price, but partner first class awards went way, way up.

Since people who want to fly first class awards want the swankiest, most aspirational flights, the increase in the partner award price is a big problem.

United Global First is good.

For flights between the US and Europe, Austrian Airlines releases its economy class award seats to partners 298 days before the flight and its business class award seats to partners 88 days before the flight.

Austrian routes between the US and Europe have economy award space up to 298 days out

Austrian is a Star Alliance member that operates five routes to North America from its hub in Vienna:

New York-JFK
Chicago
Washington-Dulles
Toronto (don't forget about routing to Europe via Canada)
Newark (begins July 2, 2014)

Austrian operates two cabin Boeing 777s and 767s

Did you miss 20k Miles (or Less) to All of South America All Year yesterday? That post is a competing trick with this one, and it might be an even better deal for you.

Chicago to Santiago "should" cost 30,000 American Airlines miles each way in economy.

October 2013 was a big month for me. The month started in Brussels. I whirlwinded through Oslo and Amsterdam before getting to Munich in time for the end of Oktoberfest.

Munich was the last stop on my eight month world tour. I landed back in the US for the first time since February just in time for the Chicago Seminars.

The Seminars were a blast, and I had a chance to check out the Park Hyatt for two nights afterwards while exploring the city.
