Of interest to those arriving to Heathrow this Thursday: UK Border Agency staff participating in massive public sector strike. Delays/queues expected at Passport Control. http://www.guardian.co.uk/politics/...ctor-strikes-air-passengers-warned-disruption Perhaps this may be big, or perhaps it's a big bust and fewer than estimated really do strike. The strike is primarly centered around teacher protests. Tube/transport strikes, originally slated for this week as well, have been cancelled. Neither BA nor AA have notices posted, and both airline offices here are taking a "watch this space" approach at the moment.
