The Belgian Govt imposed additonal taxes on short haul flights, with LGW definitely within the specificied range. Train is probably quicker/more convenient.
Short-haul, I still would very much like to see an Air France - KLM group airline - preferably KLM - come to Gatwick if they could take over the slots to be vacated by Aer Lingus at the end of the month.
Why would IAG hand over slots to a competitor when they are looking to expand their own operation?
