Hey Quinny ...
Just a thought, and this isn't meant to be argumentative or aggressive...
You're asking anonymous people on an internet forum for info. on schooling allowances etc regarding a contract you're considering signing up for.
My question simply is, isn't this all being answered for you by the amazing HR people of Dnata/EK? Surely the efficiency of such dynamic companies like these should be able to answer these simple contract/renumeration related questions?
Or....are you attempting to solicit the "facts" from guys/gals who have been in the fold of the Emirates Group for some time...and therefore have most probably been "affected" by their lack of transparency?
If the latter is the case.....Caveat Emptor
Best of luck with your decision.
