From BHD BE provide interlinging and code-share agreements, and if I'm correct, is the only airlines to currently do this from Northern Ireland at LGW.
BA codeshare on the flight, and I'm aware that Virgin Holidays use BE to interline. Other airlines also have such arrangements.
If your final destination from NI is London, you already have a vast choice of routes, times and airports, therefore BE moving to STN I see as a complete no brainer. As FRatSTN has stated there may be a use to connect to loco services from STN but again EZY would already provide this, serving the Belfast market. I would surmise that there is greater demand to connect the destinations via LGW than would be to change to STN.
Also the ability to have formal arrangements with the Gatwick carriers, rather than a loose do-it-youself connection via STN.
