There is no real need to read the small print if you are happy to stay at SIA for the full term of the Bond. This means you may have to accept over a period of 5 years from being checked out large changes in the T & C's such as increased rentals without a worthwhile increase in the allowance, currency changes not in your favour, perhaps no bonus in some years, perhaps no service increments, perhaps large increases in school fees etc etc
It will cost you dear to leave before the Bond is up. That is all those people who say read the small print are getting at.
One also has to wonder as Expat400 has already suggested whether a B744 rating will be worth the paper it is printed on in 5+ years time.Perhaps that should also be a consideration to those thinking of SIA Cargo unless they are quite old.
