Hi. I am currently planning a trip from DC to Denver. One of the cheapest (and surprisingly quickest) connecting routings WN shows me is IAD-MDW-COS-DEN, all on the same plane. Should this present any concerns to me? Especially regarding checked baggage? I assume WN has procedures ensuring a through bag gets kept on the plane, but I've never been on a routing such as this. Are there any other concerns I should think of? Thanks in advance for any thoughts.
