Is the "twittersphere" really the best place to find out?
I don't see why we cant use social media to keep up to date with any new routes.
TAP announced Manchester (and the other Euro routes it launched at the time) via Facebook first.
Thomas Cook re-confirmed on their twitt*r that MAN-LAX was still happening despite being 2 weeks before the official announcement.
Plenty of other examples too. Yes, sometimes you get the bog standard 'auto-reply' as I like to call it, but, there are times you can strike it lucky.
