Hey BHD2BFS;
check many dates BFS LHR is operated by 319 and the 320 heading to the Canaries, Malaga and Faro. Check Jul13 to 15th you will see! Also it is not uncommon at weekends.
The BFS LHR route is in for big drop in numbers this summer, as last year there were 4 x 320 each day this year it is 3 daily with some on 319, though as you say it is 320 in the main on LHR. EI carrier a respectable 32k pax on BFS LHR last July compared to 39K bmi on BHD LHR... sadly we wont see that again this July! !
