UNITE (the union behind the BAA strike threat) has called off the strike planned for the 7th of January that would have shut down Britain's main airports.
Unite said that an agreement had been reached in principle over the future of the BAA pension scheme. The agreement will be discussed by union representatives on Thursday.
If the deal is not accepted by union representatives, further 48 hour strikes on January 14 and January 18 are possible.
Maybe BA, by not warning passengers about the strike threat, knew something that BAA and UNITE didn't?
