Anyone got any insight into the latest thinking of Virgin with seat allocation - Until recently selecting seats was free, but sometime last year they announced they would charge, with the system becoming operational from the 25th June. (However selction would be free from 60 days before)

I have just seen they have decided not to introduce from tomorrow until the system can run "smoothly" - so assume they have hit technical problems.

Just wondered if anyone knows something more or when it is likely to be available?
