I think with KL in J it really depends on the crew when they're bored and/or your interaction with them. I had a relatively short hop to DUB the other day where the crew insisted on giving me more beer the entire way. It was hard to refuse, but I managed. HAM-AMS I also usually have a very happy crew, even turbulence and hitting TOD is usually not a hard marker for them to stop.

In Y, luck may vary and may much more depend on your status. As platinum and ultimate both I've always had very good interactions with the crew. But I do tend to sit towards the front / near J, where maybe you're more in view. I doubt you'll get the same service if you're in the exit row hidden between the masses.
