Apparently a lot of turbulence.
The pilot wasn't articulating very well so I couldn't understand every part of it.
[00:00] "...117, 121.5"
[00:03] "...117 in front of you. It's not getting better. We're 15 minutes ahead of you. Non-stop at the limit of the layer and we're getting once in a while some nice bumps."
[00:15] "We're getting the impression that we're getting out of it. JUST at the summit of the layer. And then it covers us back up and there it goes again. And uhh according to control [...] I asked dispatch a vertical analysis and according to control it's not good for 340, 350, 360. 380 is fine but I'm too heavy. 320 and 330 they have no [unreadable] turbulence, I've got my passengers who are throwing up everywhere. I think that if its [unreadable] I'll descend. I'll keep you updated"
