This week at MSP check-in, DL rep claimed they couldn’t thru-check onto AF flight because the connection time was more than four hours. The connection time is more than four hours but less than six hours. The domestic DL flight is on DL ticket number. Were the agents just being lazy in not wanting to do the manual work required to thru-check the bag onto onward AF-operated flights on an AF-operated ticket?
