So I don't suppose JL has original routing credit for flights other JL group right?
My final leg AA DFW-YYZ in J was delayed 3 hours and I switched to DFW-LGA-YYZ with AA/WS and in Y only. Is there anything I can claim from JL? It's not a lot of miles/FOP so I don't really care, but I'd like to know what the typical protocol is in case of future incidents.
Isn't that AA's job? You should have asked AA to post the original routing credits.
