to do what with though? Who wants to charter -200's now when everyone else is using -400's and even -800's and 777 are the new freighters du jur
Depending on the length of the trip (short 3 hour flight vs a 8 - 9 hour haul) and average cargo load a -200 might fit the bill over a -400. And I bet the charter cost of an -800 or 777 is a lot more than a -200. It all depends on need.
