After scattering my miles around several airlines last year, this year I concentrated my international travel on United got the coveted "1K" status. So I will get early boarding, first dibs on upgrading, and so on.
The thing is, to get this "honor" I had to spend a lot of time on airplanes. And to reap the rewards I have to spend more time on airplanes. And quite frankly, spending time on airplanes is getting old.
But here's the problem: there is little chance of me finding a job that doesn't require travel. My resume has 20 years of high-tech marketing/business development/sales. The tech industry is international, so any job I take in one of these areas will require some sort of domestic or international travel. And it's just going to get worse as time goes on as both production and customers move offshore. The only tech jobs that are going to be left in the U.S. are going to be something to do with accounting, sales, strategy, design, IP, or management. At at my company all of these functions travel to one degree or another (accountants have to audit our overseas holdings and IP people have to travel for depos, trials and negotiations).
So my only option is to retool to a different industry - something that is nearly impossible without starting completely over - or being unemployed. So I think I'll be seeing plenty more travel in my future.
