I've got a T3 departure in just over a week (Tues 16th), and then a T3-T3 connection the following day.
First flight isn't until nearly lunchtime. Not sure whether to turn up at 6am should things be bad (was going to drive down with the intent of arriving between 6-7am anyway - mainly to avoid some traffic). Either I'm turned away, help build up the queue, or get through relatively quickly and have a bit more drinking time.
Got around 2h20 between flights for the (HBO) connection (assuming my inbound is on time etc).
