Bet what, exactly? I already wagered and lost karma, and I'm wagering more just by replying to you.
Air travel around the Pacific Rim is down by about half a nine to 1 nine [0]. Worldwide, airlines are taking beatings of about half a nine [1], which isn't that much, one would think, but airlines famously have supposedly tight margins of about 1% [2][3], and so even a minor system shock is impactful.
Sure, 99% reduction, 2 nines, is a bold statement. I'm merely imagining what would happen if both Boeing and Airbus went under. Without their facilities and engineering knowledge, it could take decades for a competitor to ramp up. Airbus themselves took decades to ramp up against Boeing, and they were purposely assembled for that task [6].
Most Boeings in the air are a little dated in terms of design, which has led to scandals (read: "crashes and loss of life") in the past few years. Specifically, the 737s and 747s account for 77% what Boeing's got in the air [4]. Similar numbers for Airbus, with again 77% of those planes being the A320s [5]. That's a lot of planes that rely on the duopoly for not just continued production, but also maintenance; aircraft are continuously costly and require expertise and care.
