Web applications are by far the most efficient, and cheapest whom ever you use, all air carrier handlers have this facility. If you have ACARS, well then you're sorted. The handlers of course will be doing the load planning at non base locations, so they'll be in ctc with you/crew anyway. Do your crew carry laptops/palms with a printer etc? All can be used. DON'T USE SITA coms!!!!
I'm in the UK, and if I'd have to pay (domestic) for my call to a chum in NSW "OZ" for the paper via SITA, I'd be bust, thanks SKYPE!
