I tend to agree with Mile-Hor. When I'm on the road (80% of the time) all of my expenses are paid - Food, rental car, gas, incidentals, etc.. When I'm home, all of those expense are on me. I would guess I "earn" an extra $5K-$10K per year due to not incurring expenses.
I do not attribute any of this to elite status though. To me Elite Status just makes the travel time more comfortable. If I stopped travelling I would not need these benefits and thus they'd have no value.
