Depends who you work for. As a frequent business traveller myself working for a very big U.S Corp, the default travel setting on the internal booking system in the UK is LHR. A couple of years ago I did a lot of travel to the Nordics. Standard policy use LHR. Despite much cheaper travel elsewhere, eg RYR STN, approval was required to book STN and I couldn't be bothered waiting for that. Same with hotel bookings. When colleagues are coming in from the States, they will not look beyond LHR as the arrival point.
