perfect lesson why after CO tells you everything is confirmed everyone should call up (if its not indicated on COs PNR) and ask for all the PNRs of each carrier besides CO that will be flown

for an upcoming trip I have LHs,LXs and VSs PNRs thats besides COs, if they dont have them to give to you then could be the other carrier hasnt Confirmed the tkt from their end as of yet
