it's a two way street with BRU/AMS, and I'm sure EWR. My family were taking bets catching a flight back via BRU on how few people would be on board, it was nearly full, over 90% and hardly a local accent, like AMS loads of transfer pax and nearly all foreign tourists. I have to ask how they would arrive here if at all without such links being in place. EWR also is a good hub, I know plenty of people who have holidayed in Vegas and other cities and used the route - if it costs us to build/sustain such links maybe that's what needs done, people are asking for APD removal, its basically a more targeted version. Comparing EZY to KLM doesn't work, EZY being a point to point carrier with no connections, and BHD will be the choice of airport for business passenger focussed airlines for fairly obvious reasons.
