We've only recently acquired the 727's.. along with some 741's, 707's and a host of other stuff from another airline who sold them to us on the cheap. Route testing has been done on a handful but as yet.. we don't have the route structures in place (though we have enough data). Getting these new aircraft required quite a major rejig of our organisation and flight numbers so it's been a lengthy process. However.. once they're ready.. the routes will be uploaded and the aircraft will be made available for general use ;-)
