Stupid Heathrow, building a new Terminal 5 but not having any extra
capacity to operate flights with...

What they should get rid of... are the Absolutely Stupid Short-Haul
flights. Is it really that difficult to goto Euston to get a train to
Manchester/KX for Leeds/St P for East Midlands?* If only there was a
direct train to all those terminals (which would only be possible if
they combined the HEX with the Circle Line).

That way, they can free up space for longer-hauled flights. Bring on
the A380s! Out with the locals to Manchester.

*Yes I know the Picc but how much do you believe the Short-Haul Flight
Clientèle like sitting next to "commoners" from Hounslow and Feltham?
They prefer the HEX, which is far out of the price range of said
travellers.
