You're right, there's nothing about the current baggage fiasco at T1/T2 anywhere on PPrune, or anywhere else. Except, that is, for a brief paragraph on the BBC News website which covered the Queens' official opening of the new T2/Queens terminal on Monday the 23rd. The brief report states there has been severe baggage problems in T1 with many passengers departing without their baggage.
The problems started on Saturday and continued all day Sunday. By Sunday evening there were reports of app. 25,000 bags having been left behind affecting all T1/T2 departures. Many flights departed T1/T2 with no hold baggage at all. Apparently, by Monday lunchtime the airlines and handling agents had 'rushed' about 17,000 bags to their destinations but the baggage system then suffered further issues and the problems started again. Haven't heard what the figures are currently for missed bags.
There is most definately a concerted effort to keep the story out of the press. I'm guessing journalists who are enquiring are being told it's a minor issue and it's all under control. After all, with the Queen arriving to open the shiny new terminal and with the T5 opening fiasco still a recent memory, Heathrow managers must be doing everything they can to keep this out of the news.
T2 does not in fact have it's own baggage sort area. T2 checked in bags are conveyored through a connecting tunnel into the T1 baggage sort area and taken to the relevant stands from there so any problems in T1 will impact in T2.
Did hear it was a software issue.
