so to clarify ... if you’re looking for the most stops
on a single flight whose route approximates the path of one of the TCON interstates, that would seem to limit the search to NW for I-90, UA or TW for I-80, and NA for I-10
in
1961 United operated a DC-7 flight pretty much along I-80 from Idlewild (IDL) to SFO with seven stops:
- Philadelphia (PHL)
- Detroit Willow Run (YIP)
- Chicago (ORD)
- Onaha (OMA)
- Denver (DEN)
- Salt Lake City (SLC)
- Oakland (OAK)
in
1962 TWA operated a Super-G Constellation flight IDL-DCA-ORD-DEN-LAX-OAK-SFO
