West Switzerland itinerary

When you say "days" do you mean nights, as in 2 nights in Luzern or 1 night in Luzern with 2 "days" -- Do you have 9 total nights including arrival and departure? It's best to do itineraries based on nights, as days sometimes involve more than 1 location when you're moving, so it's impossible to advise.

Sorry I meant nights

With 9 nights, you need to cut down on 1 or 2 of your bases. 1 night stays aren’t a great choice, as you never have a full day to explore the area without having to move again.

Personally I’d recommend
Fly into Zurich > Zermatt 2 nights > Mürren 4 nights > Luzern 3 nights (easy day trip to Bern from here) > Fly home from Zurich

OR

Fly into Zurich > Luzern 3 nights > stop in Bern for the day on the way to Mürren 4 nights > Montreux 2 nights (visit Lausanne) > Fly out of Geneva

If you’re insistent on the split up that you have, then:
Zurich > Bern 1 > Luzern 2 > Mürren 3 > Zermatt 2 > Lausanne 1 > Fly out of Geneva

Thank you for your suggestions! We can stay more than 9 nights. I’d like to still see each area. I love idea of 4 nights in Murren.

Actually I'd say you're in central CH, not Western. That would be more like Montreux, Geneva, etc.
