Heathrow bosses today promised to learn the lessons of the disastrous Terminal 5 opening when flights begin from the new £2.5 billion Terminal 2 next year.
The T5 opening in March 2008 proved a disaster, with thousands of bags going astray and long queues for passengers.
Heathrow chiefs said today they had worked hard to learn lessons from the T5 debacle but warned there would still be "challenges" in getting T2 up and running.
We cannot promise that everything will be perfect on day one but we have a lot more experience now having opened T5. But I would not underestimate the challenge we face.
