Lots on the news about a 4 day strike by the Border Force at LHR that was to have started Saturday. We arrived at LHR T-5 this morning and went through the e-passport control with no delay. There were officers present for those with passports not eligible for the e-readers. We're flying from on BA from T-3 tomorrow and am concerned if we are going to encounter delays. Anyone have more information as to what's happening?
