Does anyone know if this is still 6 hours? The post from Gatwick in the below (from 2025) seems to suggest it was reduced to 4 hours, but interested if anyone has seen it first-hand on a BA ticket?

I'm possibly being dumped there with a 5-6 hour wait in the next few weeks, so I thought best to check whether to head straight to the terminal or wander off somewhere else first.
