This discussion has done the rounds before (if you could be bothered to find the link ..... 'coz I can't), but some things bear repeating.
If my company was to lay claim to all points and SC's generated by my travel (including CC points) then I would only impose 2 conditions. The first would be that all travel was to be completed between the hours of 8:30 to 17:30 as that is what they pay me for. And I would also need to be at my home each Friday evening and not be required to leave it until Monday morning.
So any overseas trip could be of 3 days duration only (Monday & Friday would be travelling days) and could extend no further than SEA due to flight durations.
The reality is that my company makes no such claim and so I am willing to fly out of Sydney this Saturday morning and return next Sunday morning, so that I can spend a full week in Houston. My recompense is to use personal + works points toward a couple of award tickets to the UK every other year (saving the family about $5K in airfares). If I worked it out per hour it would probably be about the right rate, so I guess you could say it is a kind of overtime payment.
Cheers,
Andrew
P.S. If you are on an AWA you are probably fecked, but serves you right for voting for the Tories.
