I'm embarrassed to say I completely missed this thread and the do, especially since Belfast is my home town.
I did suspect something was afoot since I was on the BA1415 from BHD to LHR at 1.25pm on the Sunday and there was a preponderance of Flyertalk discussion and few Flyertalk tags on bags all around me!
I was in 1C. Who was that in 1D with the fancy brown and white two tone brogues?
Gutted I missed it. Will surely be there for the next one!
