At the company I work for (also a travel company), quite a few people in the call centre work remotely simply because the business grew faster than the building. IT had already started working remotely and after a few trials management just concluded it worked well. I'm not actually sure how many people work remotely now (I work on the other side of the planet, so I can't see them).
