Such is the state of the airline business/capitalism. There are basically only two manufacturers: Boeing and Airbus. The airlines place orders years in advance and if you cancel a Boeing order now you’re a) out of a lot of money and b) joining the back of the line with Airbus. The simple reality is that the airlines (and their shareholders) consider a) and b) to be greater risks than the safety record of Boeing planes. Given the parameters they have they’re not wrong. Air travel is still incredibly safe, even if these Boeing incidents make it ever so slightly less safe. To be blunt, the market can absorb it and individual airlines have little motivation to change. If there is going to be a big change it’ll need to come from the FAA.
