Baggage halted at new £4.3bn T5
Flights from Heathrow's new £4.3bn Terminal 5 are departing with hand baggage only after luggage check-in was suspended due to a processing backlog.
British Airways, which has sole use of T5, announced check-in of all hold luggage was suspended until Friday.
The airline has already cancelled 34 flights because of baggage problems and passengers have had to wait up to four hours to reclaim their luggage.
BA said it "sincerely" apologised to all those customers affected.
