I always read that the TrueBlue program is not as beneficial because you earn arbitrary points rather than miles. I earned my first TrueBlue Award in January this year. Looking at how I got the award, I am seeing the following:

10 flights were between JFK and BNA (4 points each)
4 flights between JFK and BUF (2 points each)
1 flight between BNA and ROC (4 points)
Plus all the online booking bonuses.

So that is 15 one way flights total. If I had gotten miles insteasd on the legacy airline I sometimes fly, that would be

10 * 889 miles between LGA and BNA (764 actual miles, 125 economy bonus)
4 * 500 miles between LGA and BUF (the actual flight is less than 500 miles)
Approx 1389 (889 + 500) between BNA and ROC

Add all those up and I earned approximately 12,279 miles, including their mile bonuses. That isn't enough for a free flight on any legacy. That's barely halfway to a free flight on a legacy, assuming its 25,000 for a free flight in continental USA.

Am I missing something? I feel better off with JetBlue in this scenario, although I haven't used my voucher yet (I tried, but didn't act quickly enough).
