My airline, Aqualantic Express, is replacing older (owned) A330-300s with new (also owned) A330-900neos. After replacing a few routes, I realized the new aircraft wasn't making as much money as the older one. They are in the same cabin configuration, 6F, 48C and 296Y. Does anyone know why this is happening? (I couldn't find another thread on this, if there is I am sorry. This is my first post!)
