At work today the wall boards mentioned IB crew were on strike causing havoc at Terminal 1.
The terminal staff in T2 first thought there was a baggage strike in MAD so stopped checking passengers in. We then got info it was crew who were on strike.
Terminal 1 was packed im told. We did not get many calls, so i assume LHR handled it well. Does anyone have further info on why this happened and will it happen again.
