Heathrow Terminal 2

Travelled to Dusseldorf via Heathrow on Monday night - Terminal 2 @ Heathrow is probably the worst piece of airport in the UK. Fortunately there wasn't the 750m queue for security on Monday night but the intense heat of the building beyond makes you feel like you are in a sauna. All shops/and sitting areas have really cramped feel, all set at slightly different levels.
Evening crowned by Lufthansa sending an HS146, so it was pretty cramped. Key thing with RJ100 / HS146 if you are sitting in rows 6-11 is to get your hand luggage in rows 1-5, because the lockers in 6-11 are very narrow due to the "over wing design"
