From what I've heard, get in the queue 20 seconds before they go on sale. If you don't get in after that, refresh like mad. On See Tickets/G&T, the queue isn't actually a queue. Open spots are allocated randomly to those who refresh/have their timer run out when a spot is available.
I dont know if I should follow this up or not. I wanna give out this freaking ticket that I accidentally clicked on this morning. I felt a huge regret. Coldplay, you surprise AND DISAPPOINT ME AT THE SAME TIME.
