Altimeter - how to properly set up?

So I got onto a plane today, then drove through a region with quite some elevation. My watch claimed I never change elevation of 28m above sea level at all today.
Can anyone advice me on how to set the altimeter up properly? Which settings to use, which calibration method?

Just as relevant for the Fenix 6

Wha/t do you recommend for Auto Cal During Activity and Not During Activity? And Watch Mode Altimeter, Barometer or Auto?

I periodically update elevation using DES setting. It uses the map rather than GPS for accuracy.

I have mine set to Continuous during activity and On Not During Activity with watch mode in Auto.That works for me.

However, others will suggest otherwise...

There is a big discussion for the calibration of the barometer where some people give advice on how to calibrate the barometer-altimeter. There is too much information. forums.garmin.com/.../calibrate-local-barometer

Personally, I manipulate the watch mode manually due to several reasons:

I live at almost sea level and I know the altitud references for the area around me

Pressure changes rapidly some days where i live and in auto mode affects the altitud level of the watch

I found it more accurate: when I'm at home in barometer mode and when I'm moving in Altitud mode.

Again, I do this because is easy at sea level. When you live at few hundred feet/metres the accuracy can be relative as depend on how you set up your barometric pressure which is explained in the thread I pasted above.
