It's only shut from 2300-0545 so unless things are running rather late it shouldn't affect them.
Except for that one instance a couple of weeks ago in the afternoon when due to surface break-up 06/24 was closed then everything did divert to GLA.
12/30 was available but visibility wasn't great hence the diverts, but that didn't stop all the Execs making it in no bother. In fairness it was a BACF ARJ that was the first to brave 12/30 before 06/24 re-opened.
The 0500 MON ZTH departure chickened out of using 12/30 last week and departed late using 24 pretty much as soon as it re-opened. Whether being able to use 24 was the reason for the delay, I don't know.
