I have flown Southwest for years, my favorite and often my only airline. That said, I am also concerned about possible issues with the MAX. Yes, I know that compared to these two incidents, there have been thousands of other successful flights, and yes, I also know that statistically, I am probably more at risk driving to the airport than I am in the air. Sometimes irrational caution takes precedence over logical reasoning. I was already a little uneasy with SWA's outsourcing of maintenance and the longstanding lack of contract with the domestic maintenance people.
Am I going to cancel any truly necessary flights? Probably not, but I am reevaluating a lot of my discretionary travel, and yes, I am looking at the type of airplane. That in itself is probably an exercise in futility, with SWA's frequent equipment swaps, so perhaps its time to expand out to other carriers again.
