Even as I get older, I cannot feel any change in the cabin air. So electric or bleed or anything else? Nope!!
65 years of traveling in various aircraft and like you, I too can't notice any difference long haul.
Feels just as knackered irrespective of aircrsft type with the class of travel being the only doscriminater.
