I'm at the same point, except a Nikon user. I like having my full frame DSLR, but as I get older, traveling by air, or hiking with all that extra weight is something I want to get away from. I've considered a mirrorless body, but that doesn't offer much of a weight advantage, unless you switch to all mirrorless lens, and even then, it's still heavy. But when you've been into photography for 50+ years, you know a phone, regardless of how good they might seem to a causal user, don't really cut it for everyone.

So now I'm looking at APSC or Micro 4/3's as possible travel solution: lighter weight, smaller size, lower cost generally. Of course, as you move to smaller sensors you lose some low light capability, but with the newer in-camera and lens stabilization some of that can be overcome. Also, some of the denoising software routines have gotten so good.
