but understand that LGW's growth is driven by easyJet and Norwegian, both loco leisure. LHR serves a slightly different market in connecting UK business to the world
Of course, we all know that a 3-times weekly service from Heathrow to a secondary city in China is going to contribute far more to the economy than an extra 15-20 aircraft that easyJet and Norwegian could base at LGW with an extra runway
And if you think easyJet only serve the "loco leisure" market, you're a little behind the times.
