Its not just delivery While each aircraft delivered brings in more money, lets not forget that after market is making money too. With Netjet at max capacity and can't sell more jet cards their airplanes are utilized to max. That means more hours on airplane and more maintenance. Flex jet is also in similar situation. Used bizz jet are geting sold quickly and they require refresh too. Bombardier is gaining on both front. New jet orders, and huge demand on after market support. Delta variant had an unexpected boon to bizz jet industry. The longer it takes airlines to recover the better it gets for bizz jet. Also once clients get used to bizz jet, then they might not want to go back to commercial. Time will tell but for now it's power play for bizz jet.
