I know that a few years ago Runway 2 (05R/23L) was in operation from 06:00-12:00, and then again from 15:00-21:00 local time, Daily!
That was then changed to 06:30-10:30, and then again from 16:00-20:00 local time Mon-Fri. Then it is just 06:30-10:30 on Sat, and then only 16:00-20:00 on Sun. (So it would go about 30 hours with single runway ops.) I'm not entirely sure why they cut its use that much though.
I wasn't aware it had increased recently by 3 hours a day. Are the weekend times still the same as before? And are the longer opening hours here to stay?
