I thought this forum was about planes and that stuff...I am from Barcelona, I was grown up in Venezuela so I didn't speak Catalan until I was ten years old and I've never had any problem, neither in BCN
nor in other parts of Catalonia.
Anyway, I don't see the problem on writing an article in Catalan, because the source you've taken is from there, i'm sure it also had an Spanish version, maybe you didn't search enough.
And if all of us were to tell everything we hate with such easiness this would turn into a very unpleasant forum...
Finally and returning to the original idea MHO is that BCN
is a perfect place for such a HUB, it's a great city with a great airport that now is starting to play the role it should have been playing for years, but neither Iberia nor the Government wanted...
Thanks to all
