NuPhy Air 60 with Aloe switches should do the trick. NuPhy feels and sounds a lot better than Keychron in general, and Aloe switches are light linears that you'll barely hear.

I know I'm late to the party, but I've just ordered the new lofree flow, a low profile keeb.
I use a Planck keyboard which weighs just under 300g with Kailh box switches and XDA keycaps. It's labeled as a 40% keyboard so I was reluctant at first, coming from 65% myself. But since the keys are smaller, especially the space bar, it still has a relatively high number of total keys given the small form factor (there's even space for arrow keys!) and having your layer switch keys right next to the space bar for your thumbs is very comfy IMO. I ended up liking it so much that I use it daily and now I'm wondering what to do with my main keeb. If you're up to trying something new, you can have a look at some layouts. The keyboard looks inconveniently small but once you see the layer layouts, you'll see it makes a lot of sense actually!
I have an ortholinear kit I built but it's caseless so it's not suuuper portable. Which Planck do you recommend? I'd be willing to give a 40% a try even if it's not for this trip. I'm okay with soldering if it's a kit and/or there's decent instructions.
I went the easy route and got a Planck EZ because of the plastic case design where the upper part of the case is the plate. It's super lightweight which was my no. 1 priority. I got mine used but if you plan to buy new, it'll be discontinued soon, just a heads-up. I've seen some Planck-style kits on Aliexpress, some with aluminium, some with plastic cases, but haven't tried them myself.
