Hi,

I'm flying back from SIN to LHR tomorrow night (BA 018) on what appears to be a completely full flight in all classes. I'm booked in WT+, and already have a good seat allocated. My experience with flights this busy in the past has usually (about 75% of the time) been that I got upgraded - this is what happened on the outbound flight yesterday. Will OLCI make this more or less likely to happen, do you know? Or am I better off just turning up at the airport and seeing what happens then? Usually I'd use OLCI just to ensure that I get a good seat anyway, but since I already have one here I'm not so sure. Any thoughts? (and my sincere apologies for mentioning the U word, it won't happen again!)

Thanks a lot!
