Yeh, IATA don't have a normalised data model, so you're badly out of
luck there. 

There are some reasonable books on Data Modelling from Wiley you can get
with fair models in, plus Kimball has a simplified data model in his
Toolkit book.

I'd make sure you get your requirements straight, otherwise the data
model will grow and grow as each new strange-but-true wierdness emerges.
