Q1
Yes!
Q2
I think this would be counter productive if it became like many social media channels where people post their complaints directly to them. I'm all for contacting a twitter team etc, but imo that's not what this forum should be. A rep may attract people who feel they've not been heard (read:recent post demanding compensation for a 45 minute delay). We should have some ground rules to try combat that.
On the positive side, it would be good to hear about new routes, lounge expansions, new wine and seasonal menus on the ground and on board. I think it would be good to have a link on the dashboard to the 'Official EK rep page', if it happens.
Q3
Flyertalk of course. Even googling my EK question will throw up an answer that's already come up on this board.
so: Flyertalk, Google, EK Website, Facebook, Twitter and Instagram if I want to know what happened 2 weeks ago.
