Travel (health) insurance (~$125/ month) is often my PRIMARY health insurance ($2800/ month A(?)CA)
They are not keen on that, but.... I play within the rules.
I have never planned a trip more than one month out, so never needed to cancel (yet).
Our RTW was ... " It is getting kinda cold here, Where do you want to go next?"
I just look for bargain fares.
Yesterday I found a SAME DAY fare that was $49 for a 4 hour flight. Poof, GONE!
