Nights from home was just an example.
Number of trips.
Number and level of loyalty programs.
75,000 Air Miles
etc etc
The point is that if it is being "refocused" to a strict miles and points IBB, I have strong feelings that the TB out to be traveling more than three times a year to go see grandma. With the focus we should expect to see travelers.
Thinking about this, maybe just asking this as the "debate" questions would suffice. But there should be a minimum. We certainly have no way of verifying, other than honesty. 25% Travel would be fifteen trips and or 50 nights per year. Something along those lines.
