Yes - I think we were C36. We were called to the gate REALLY early!! Scheduled to depart for Southend at 2055hrs. but still had plenty of time for a few pints of Strongbow at 6.50 Euros from the Sportsbar!!
We were also called to the Gate really early. By the time we made it to C40 we were boarding, but the fact was we waited in the Ramp section just before the Airbridge for ages. We usually fly Monarch and with them we just sail through this bit. Weird. I saw this happen when we arrived at Gate B13 on the way out, loads of passengers on the ramp just waiting to get on.
Oh and if it was the Gate right at the End of Pier C on the right, that's C37/C39 (It's basically the same gate). I'm sure a Ryanair to Stansted was at C36. I remeber actually because I think someone hadn't turned up for the Southend Flight and there were a few calls for someone to go straight there haha
