Update: we have some official photos from the Heathrow Terminal 5 opening over on the website.
This virtual tour of Heathrow Terminal 5 is a good few months old, but it's a decent substitute if, like TW Blog, you'd rather be attending today's opening than sitting at your desk.
This morning a BBC reporter asked Willie Walsh whether it's fair that BA is being 'gifted' the terminal.
He said yes, of course, pointing out that it brings most of BA's Heathrow operations under one roof, a situation other airlines already enjoy.
Still... look at Terminal 5. Then look at the other terminals. Does it still look completely fair?
Predictably, Virgin Atlantic is among those who don't think so. Here's director Paul Charles speaking to the BBC:
It may be a wonderful new piece of infrastructure and architecture, but it doesn't do anything for most of the airlines that operate at Heathrow. This is a gift for BA.

It only makes sense to put all of BA's operations under one roof. What they should be doing though is razing and starting from scratch the other terminals, one terminal at a time. Just renovating terminals every decade is part of what makes Heathrow look so shabby.
