I finished an 18-jump trade mission between Eo's Garden and Edras, carrying 104cu of Xi-Rite, and was rewarded with the following:

17,000c
19,000 trade XP
350 Itani faction points (Itani standing increased massively)

hot damn, but that's a nice run!

Heh, at least they didn't give you one to Deneb :P

I kinda wish they had. It would've made the trip that much more worthwhile.

I'd done one for Xi-Rite to Deneb. Got 20000 trade XP for it (LEVEL UP!), 0 standing (which was what I actually wanted). Of course, I was already at 65535 out of 65536 Itani standing....

17,000c? I got 126,000c for doing a 9-system 108cu bulk mission...

18 JUMPS!?... Surely you dont mean 18 WH jumps. Thats just stoopid. Anyway 17,000c isnt all that much actually I wouldve thought youdve gotten quite a bit more. Although Im sure you were similar to feeling the way I did in that you would have done it simply for the XP and standing increase alone. +350 standing with any nation/corporation is very nice indeed!

the most xp i've known is +21600 for a "5" jump mission

I don't remember exactly when (It may have been before the trade XP nerf) but i got about 22000 trade XP for a mission. I've also gotten 150000+ credits for a single mission... (Not including the bonus)
