Im talking about within the last 10 years or so, not back in the pioneering days of air travel - or helicopters.
Yesterday, the regular scheduled flights by KD Air from YVR to Qualicum Beach were operated by their Cessna 172 instead of the usual PA31 Navajo. Even then, one of the flights only had a 66.666666666% load factor!
Any other examples where light aircraft have operated scheduled flights??
