A couple of points - I've used these promotions before - generally you have to hand in the tokens at checkin - and in my experience the checkin staff don't even ask for them. Especially if you're travelling many months after the promotion started (The Go promotion runs till March). I guess you could just say you left them at home if asked.

Secondly, depending on when you travel you may be able to get similar deals by waiting for Go's next promotion. There will invariably be plenty over the winter months - there certainly were last year. Same with Buzz, Easyjet and Ryanair (who seem to have a different promotion every other day).

The Times/Go promotion also does allow travel outbound Friday or inbound Sunday, and there's not always availablity on other days, so I've ended up deciding it's not worth the bother.
