Flights on a codeshare's do not always map to the same fare class in the ffp.
3 ffp is one alliance is a lot. Having multiple ffp’s with low balances is never a good idea. You never get enough ff miles/points to be of use before they expire. FFP’s are for the long term. However at times it makes sense to have a ff membership with an airline in another alliance. (e.g. Oneworld & Star)
