Glad I can rate something good
Quite busy in some areas. Some restaurants required you to share tables with other parties due to lack of space. If you were travelling with a larger group (4+) there was little chance of you managing to find space before boarding your flight. However the food was served very quickly and a good price.
A long walk
Small departure lounge pretty busy could be bigger
Didnit enjoy my experience especially since I had to pay extra for checked in luggage food and beverage !!
Not the prettiest airport in the world. Heathrow Ltd. could do more to spruce up softlandscaping and outside areas in general.
