I use Black Diamond telescoping poles with the click lock device - never had a problem with them collapsing under me when in use. Other brands - Leki, Klomperdell, etc., have similar locking devices - maybe worth checking out?
Do any of the pole manufacturers make a ‘transit bag’? You’d think there was a demand so maybe there is such a thing. An internet search beckons! Our alternate method is to strap the poles to our backpacks, with ferrules on (the rubber protective tips, although in an emergency I have used wine bottle corks and micropore tape!) and put the whole thing into a flight transit bag (they are definitely a thing!) and check the whole thing in (if you are having to check the poles, then why not?).
