on Schengen airports of entry in Switzerland are: Zurich, Altenrhein, Samedan, Bern, Grenchen, Geneva and Sion (and Basle if you count that as a Swiss airport)
Isn't Lugano a valid non Shengen airport of entry as well ?
yes you are right, Lugano as well. Can't correct the original message anymore, but you are absolutely correct.
