Plodding Along
You raise some good points worthy of rsponse from BASSA, but let's face it - that won't happen (you'll get accused of BASSA bashing!)
All you could expect is the standard BASSA response of figures fiddled by BA / price fixing fines / poor fuel hedging / greedy pilots / what recession?? (Delete as appropriate)
I am sorry but BASSA are absolutely clear that they have the support of the membership when they voted (I use the term losely) at Kempton Park for NO cost savings. That, IMHO, means that you will NEVER get BASSA back to the negotiating table to work something out as it would be the same as admitting defeat.
They have lead their members up a creek then have sold the paddle in an attempt to preserve the terms of the few at the top of the tree.
