AsI understand it this is nothing to do with the EU per se, it is a European Court.
It's not the flights, it's which flights. Largely Far East and largely BA, these flights are disproportionately business-oriented. Very bad news for employees of the hundreds of FE companies along the M4 strip.
Likely loser LHR, thus London - no 2 world business centre.
Likely winners? AMS? CDG? (it's out of town after all) FRA?
I despair of this, and I live 20 miles west of LHR under the 09L approach.
