Santito,
Depends on how you look at it...
This now offers us something new to sell to the US, since CO left. Plus with the added benefit of travelling in the right direction (as opposed to CDG/AMS) plus the possibility of pre clearence in DUB, I would say it was fairly good news!
At the end of the day, it is a new route for BRS and it shows that EI must have some faith in the airport. There was a market for the US even at the time CO pulled the route and I think EI have been smart to have recognised this and jumped in pretty quickly.
With the extra KLM service as well, congrats to all at BRS who have obviously worked hard to secure a new service and prove there is a need for extra capacity.
Look at it the other way, it could have been an airline pulling out, now that would not be exciting!
