As I now understand it (from the Beeb) the BAA staff strike ballot results are not in until 20 December and a statutory 7 day notice of a strike will put 27 Dec as the earliest day for labour to be withdrawn.
When I couldn't find this out a month or two ago (see my post #342 above), I booked my LHR - ORD for 15 December and decided to have an extra week in the USA for Christmas.
