Chosen seats but considering upgrade...

So I have paid the £100 to choose my 2 WT+ seats online, now there is an offer for Club and I am debating it but am wondering will I be able to choose my seats online without the extra charge once more? Anyone know the deal with this?

Thanks, Chris

Your best approach is to post this in the BA EC forum on FlyerTalk ... that said, there are some very knowledgeable BA flyers around here who may help, FlyerTalk just may prove quicker.
