Unions Unite and the Public and Commercial Services Union met in emergency talks with BAA yesterday.
Both unions had planned to strike for 24 hours on 7 January. Further strikes, for 24 hours on 14 January, and 48 hours on 17 January could still be averted if union members agree later this week. The strikes would have crippled BAA's services at Heathrow, Gatwick, Stansted, Southampton, Edinburgh, Glasgow and Aberdeen.
According to a BAA spokesperson. "Following a productive discussion on the 31st December, BAA and the trade unions have reached an agreement in principle.
"The trade unions will now consult their members on the proposed agreement and, to allow sufficient time for that, have agreed to call off the industrial action planned for 7th January 2008. BAA and the trade unions will meet again on Friday 4th January."
