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.
