In light of United's announcement last week a number of people pointed out that the new revenue requirements only apply to US rules, so one could easily change their address to an international address and not be impacted. While on the surface this seems like an easy solution, it's prudent to be aware of the risk.
In talking to a friend last week about this we got into a discussion and I pointed out that with what companies can do with data analysis now, is far beyond anything they've been able to do in the past. Quite frankly, United could use their data warehouse to identify anyone who has "moved" out of the US and analyze their travel patterns to see if they match with the member's new address.
So what's the big deal even if they can figure it out? Easy, it's considered fraud. United could easily use the fraud justification to suspend and most likely terminate the offending Mileage Plus accounts. In recent months more and more people are finding themselves with suspended and terminated accounts for violating the terms of the program.
So, before you decide to "move", just be aware of the risk you're taking.
