The impression from VS is that these flights are ferrying from MAN empty, the loads are just GLA-MCO!!!!
As for the market from GLA, if they can sell 7 x 767's & 3 x 743's plus all the other charter flights, VS could easily fill 2 or 3 744's a week.
GLAGAZ, are those times correct?? Landing at GLA = 12:50 then MAN = 13:50, that's going to be a great transit to see!!!!!!!! Got to agree about the 744 though, if one of those JT9 powered 743's can drag themselves into the sky at GLA, a 744 will have no trouble.
