I'm leaving out many smaller stations without non-stop service that also have cheaper roundtrip fares.
Agreed. My message wasn’t that every itinerary prices like mine, but that they could, so one should always price things out.
Caveat emptor remains the rule of the day. (Additionally, fare rules are in general more restrictive for international flights.)
