Any thoughts on whether these seats are worth a go for Aug 23rd? vailability on ticketmaster just now, or hang on and hope for a floor seat?

Just tried t/master and was getting block 106 lower tier.

I am sure it has been stated before that it would be very unlikely that better seats would become available through general sales, probably might come through hotel packages etc.

People on here will know better than me thou.

Try the ALL SOLD OUT section on this site. I've seen ok tickets being sold to other fans at face value there.

I got an HH ticket on block 106 or 107 - does anybody know what the AA-HH thing means,i.e. how does it differ from regular A-H?

there's no AA, just BB - HH. they're in front of row A in those two blocks.
(the last time i checked, the TM UK seating chart had been updated to show exactly where they are.)

Those are pretty good seats, although the main stage is far away b/c the O2 is a pretty big arena. Of course, anything is better than a stadium.
