When I was young I prioritized time efficiency over all else - and given my status with the airlines it always worked.... Fast forward 20 years and now I am the opposite -- it's not about managing my time -- it's about managing my stress -- and even as a GS on UA (and the highest level status on multiple airlines) - service just isn't what it used to be - so I allocate a few extra hours that I can spend in the PL -- and I have a much more enjoyable life experience....

OP -- you are both right and wrong -- in a perfect world you were right... In the real world -- you missed your holiday.... To me it's a simple choice these days -- travel isn't what it used to be -- or what it should be -- so I allocate a few extra hours per flight - but I realize that I didn't always feel this way....
