I kinda got burned by SW my first time flying with them, last month.
Flew from Wichita to DC via STL. On the way back, i hadn't noticed, but the plane made a stop in Chicago before getting to STL. I don't think it showed up as a 2nd stop in
Momondo though i should have been tipped off by the long transit time.
I remember thinking it sounded novel to stop the plane, let people off, and let others on, while you get to keep napping/boozing/watching a movie but i guess i always thought of it in terms of it being a stop in service to your final destination (i.e - ICT to a stop in STL to resuming flight to DCA) but in practice it just felt like having to stop in Chicago for no reason.
