For heavens sake, we get it that they are all international airports - no need to mention it against each airport. If they weren't international they wouldn't be served, would they?
Secondly, nobody (well ok, very few) knows it as "Comodoro Arturo Merino Benítez". I go0gled it and found out you meant Santiago, Chile (SCL) - why don't you just use that name?
I can work out Brasilia and Recife, but as for the rest - haven't a clue and can't be bothered to find out, as I doubt can many others, so it's unlikely to result in many positive responses.
As for the comment about your smoking habits, I'll give you the benefit of the doubt, you are young and probably mean well, but you just come across as an idiot.
As to how to register as a different user name, well, you seem to have managed to register originally. Just re-register with a different name using the same procedure. In fact, (see Racedo's post below), you maybe would prefer no-one to see your posting history
