For those thinking about KAL I will repeat something I posted on another (similar) thread:
On another aircraft type in the KAL fleet there were/are 5 agencies looking: Rishworth, CCL, GAP, EuroPacific and IAC.
Rishworth were the lowest payers per month albeit there was only USD $190.00 difference from highest to lowest, some provided a small ($3000) bonus, slight differences in how the agencies structured their T&C's so different agencies could be more appealing to each individual depending on their personal priorities.
Of course all the agencies provided "indicative" T&C's, come crunch time the actual contract could be the same or contain subtle (or not-so-subtle) variations.
Would be very surprised if only one agency was to be a sole provider for the 747.
Hope you all do your homework before getting close to signing on any dotted line!
