The gray area on this is the carrier - does a codeshare count as operated by a US carrier? I was once routed LAX-MEX-JFK when all LAX-JFK were full, with all flights being on mexicana metal with AA flt. numbers. Out of curiosity, I emailed them afterwards and DOT responded that the issue is ambiguous (and probably not that big of a deal)
