No holiday on 13th.
For RWY 31, the shortest possible taxi time (stand 16, first flight at 04:50Z) is 10 minutes.
However, from stand 2 at peak hour, it was 20 minutes from intial pushback call to line-up clearance.
At the time being, flow management is applied with standard taxi times of 10 minutes. So, accordingly your CTOT would be ETD + 10 minutes. Unless you are #1 to taxi and line-up, this is unachievable. Slots are valid 10 minutes overdue the latest, so at peak hours aim to push-back on time the latest in order to not to miss it. If the regulation is in place only for PRG delays, ATC is unhappy but they do let us go even past the slot (so far).
Be advised, that TWY "H" that leads past the new pier has NO TWY LIGHTING and yellow paint marking is smudged.. "H" serves for RWY 31 outbound traffic. The usual taxi routing is (A), B, H, L, cross RWY 22/02 (defunct, but still marked), holding position RWY 31.
There's a left turn from "H" to "L" on the edge of apron, but the "L" turnoff marking is less than optimal (and no lights on "H"). Brief thoroughly, should you continue straight ahead, you're on "F" or "G" face-to-face with traffic vacating the runway. It is an incursion waiting to happen, let's not get famous.
Fly safe!
