You guys have been a great asset to my flying expericance! Thanks so much


So heres the deal, I fly to London next Tuesday... I orginally asked this question out of curiosity as my plane is a three class 777, lo and behold it is now a four class 777 being used as a three class plane, with the First seats being blocked out.

What worries me is that even before the switch the flight was zeroed out in evrey fare class. Now there are even less seats on the plane. 229 vs. 275, now this is mainly due to the fact more premium seats are being added since I'm in club, im not to worried, but there will probally be a lot of unhappy passengers. But I am worried due to the fact that I am on an BA miles ticket that I will be bumped. I am pretty sure the First cabin will be opened due to the fact that the flight looks oversold.

Just a few questions:
---- Can phone agents open blocked seats?
---- If they can't could they add a note onto the PNR?
---- If the FIRST seats show availible at online check-in, should I take them?
---- If not, should I inquire politely at the airport, or will they be reserved for Gold and Full Fare J (possible due to the fact J fare class is sold out)
---- What is possiblitlity of being bumped? (there are three of us)


Anyone else been in a similar situation...

Sorry to be a pain,

Thanks again and God Bless
