In light of reports about the Boeing 737 MAX being involved in two similar crashes and experts in the flying community expressing concern about whether it's safe, I want to avoid flying on this type of aircraft. I have three flights booked next month and I cannot find any information at all about what type of planes Southwest plans to use. Other airlines, like Delta, show this kind of information. Is it available anywhere from Southwest, or do I need to cancel my Southwest flights and book with an airline that I know won't be using a MAX plane?
