I think a free to play system could work, just not sure how the coading would go.
Lets say the free players login and have the option to fly a limited set of planes/vehicles.

I doubt that it would get a considerable number of new/additional players. I do, however, see the danger that with that list, many paying members could jump to the free account, especially some of the "seasoned" vets.
Being always short on money, I know I would

Another general remark. It seems that some here may think that at offpeak, non us prime time it's only non-us players flying and fighting. And the lack of numbers at that time is caused by a lack of non-us players.
I don't think that's correct. There have always been a lot Americans around at those times as well, possibly even the majority? It's overall numbers that went down compared to the Golden Days. It's just more notable at off-peak times, because the gameplay is affected much more strongly when the attendance drops a certain "minimum" level.
