Your quote merely says the introduction of the 787 will allow Thomson to fly from the airports listed, not that it will immediately do so from all of them.
At some point in the future most if not all these airports may well see the 787.
The only concrete information from Thomson as to UK airports is the announcement of the TOM MD Chris Browne on 19 July 2010 and, as I pointed out, CWL was not one of the initial group.
