Verrrrry interrrrresting. Totally unrelated. In a former life, while biz traveling, I found myself on a Bom-bar-dee-yay commuter jet for a hop of several hundred miles. I came away from that convinced that it was one of the most pleasant jet rides I’d ever had. I usually suffer painful blocked ears, etc., which is related to whether their pressurization of the cabin is worth a bleep or not. On and after the Bombardier flight I experienced NO discomforts at all. FWIW.
