I flew JFK-->AMS-->HER. The first leg was operated by KLM and the second by Transavia. I bought my ticket through Delta. At JFK, they checked my bag all the way to HER, even though my layover at AMS was 22 hours. Upon arrival at HER, my bag did not arrive. I filed the usual "Property Irregularity Report" and there has yet to be news.
Was I supposed to have picked up my bag in AMS even though it was tagged all the way to HER? Was it a mistake of the check-in staff at JFK to through check it on such a long (overnight) layover? (I was not at all surprised it didn't make it to HER). Is there anyone else I can contact besides to keep checking back with the lost luggage office at HER? (I know how to check the status on worldtracer). Would it be helpful to call the AMS airport lost and found? or Delta or KLM?
