Heathrow T4 Baggage System Breaks Down
The Teminal 4 baggage system is temporarily experiencing a reduction in capacity caused by a software problem. While every effort is being made to rectify the problem, you may experience some delays when departing today.
If you are travelling through Terminal 4 today, please check with your airline before leaving for the airport and consider minimising the amount of hold luggage you check in for your journey.
