My money is on BHX. BA had "sound" economic reasons for pulling Belfast*, even though bmi seem to be creaming it in. BHX is extremely popular and it is clear that Connect will only operate from regional hubs....
Of course, I could be wrong
*This was done to death on a thread here back in 2002.
Details from Connect website are: -
The BA Connect product will operate from UK regional airports. British Airways services at London City, Heathrow and Gatwick**, will continue to offer complimentary food on all routes and a Club Europe cabin on the European network.
** With the exception of the Gatwick-Inverness and Gatwick-Isle of Man services, which are operated by BA Connect
