I’ll answer your questions in succession;

1) That’s really a subjective thing and also depends on the industry that’s being discussed, I know my Dutch counterparts are always overwhelmed by how cheap things are here.

2) I believe the EU stopped (or are trying to stop) all that, which is why so many regional airports across Europe rely so heavily on Ryanair’s custom.

3) With regard to Heathrow, no other airport does more with less – period. It’s hard to really see how Heathrow could be any more efficient as it stands at the moment.

4) The unrivaled growth potential of London and the UK over the next couple of decades compared to other western European countries will mean if a business wants to invest in the UK, it will. An overcrowded airport is not a deal breaker when you’re trying to get into the region’s fastest growing economy.

The truth is, if you book early enough, Heathrow and London airports as a whole are still the cheapest option when travelling to all four corners of the globe compared to CDG and AMS (and often FRA as well).
