The New York Times mentions one of the neat tricks about international travel. If you’re going to buy a business class ticket somewhere, it’s often no more expensive to buy a business class round-the-world ticket and get a lot of extra flying for free. Where you buy the ticket and start the journey makes a ton of difference in the cost, as the Upgrade Travel Blog observes:

Start in Sri Lanka. If you’re going around the world twice or more, consider buying the second (and third, etc.) ticket someplace like Colombo, Sri Lanka. I’m not kidding. You can buy a business class RTW ticket there for about the same price as a coach RTW ticket in the US or most of Europe, on the same airlines. The article mentions this, but it’s really worth driving home.

And if you’re buying lots of premium class international tickets, consider crediting miles to the bmi program.
