Yes, the seating charts are very confusing and are all slightly different from one another.
I just confirmed this with Ticketmaster Customer Services:
Seats go row A, B, C, D..etc to ..X, Y, Z, AA, BB, CC..etc. So row "AA" is the 25th row. (As there is no "Row I" and no "Row O".)
Which is EXTREMELY annoying because for a second I thought I'd scored front row seats when I got "BLOCK AA, ROW AA." The Ticketmaster Customer Services guy had the honour of bursting my bubble.
I was simultaneously calling the "0870 903 9033" number (which seemed to be permanently lacking any free operators) and checking Ticketmaster, which repeatedly insisted that there were no more seats available for the premium price! After about 20 "re-tries" it started bringing up seats in the raised levels alongside Lindsey, and then at about 9:10am Block AA seats started magically showing up.
I managed to get two seats in row Y and two seats in row AA, both Block AA. Could've been better, but anyone who's managed to get seats in Block AA or the first half of Block BB should count themselves lucky, because Earls Court is HUUUGE and getting Block DD or Block EE is not the equivalent of getting "back of the floor" in the States: the people on the stage look like tiny dots from the back of Earls Court One.
Fingers crossed for the second night.
