I'm not compensated for the 430am alarms and midnight touchdowns that come with business travel, so I believe my frequent flyer miles are just that: mine.

Also, while working -- and traveling -- the occasional weekend is part of the deal, I make it plain to employers that I will not stay over on a Saturday night simply to save the company a few hundred bucks. Unless the sky is falling on some client or proposal, I come home Friday night. Family comes first. I wouldn't work for a company that didn't share that view.

I guess I must be lucky.
Our company lets us keep all miles that we accrue, and also wants us to make travel arrangements so that we are travelling during normal business hours, thus less time away from family. Our company is very family oriented and if our stay requires us to be at the client over a weekend, we are allowed to fly home and back for the weekend, or to another city if it is cheaper. Thus often times I am flying to another city to spend the weekend with my wife, sans kids, as her ticket and mine to that city are often less than my ticket back home. http://www.flyertalk.com/forum/smile.gif

I could not imagine an employer asking an employee to go through the hassle of setting up and maintaining a frequent flier account and then not allowing that employee use of the miles... http://www.flyertalk.com/forum/confused.gif

Imagine it! When decisions about such topics as "Whose miles are they, anyway?" are made by people who DON'T travel, it can, and does, happen. I went through rounds and rounds of discussions about that very topic, because I had a board made up primarily of folks who rarely left home. They simply don't have any idea that business travel ISN'T all fun and games, and they don't necessarily sympathize with the "time away from my family" explanation.
