My HKG flight in first cancelled. I called in within a few minutes of getting the text message. I got through almost immediately to a lovely lady on the GGL line who booked me in about 10 seconds onto the Cathay flight also in first at about the same time. I am happy with the way BA have managed this. At least by cancelling 15 days out there are seats available on other services, personally I am just interested in getting where I want when I wanted rather than any EU bonuses and I don't really care who drives the bus. Good luck to all in rearranging their itineraries.
