Lost Item No.: 1154392 - John F Kennedy International Airport, New York, US

I forgot my black chest bag/ hipbag (brand: Pinqponq) on the plane - flight number N0602 / seat 30J. The flight was 28th October, 11.55 PM. We landed in Germany (Berlin) 29th October 12AM. I already wrote an email to Norse, but they don’t answer. And I wrote to the lost and found place at the BER (and went there yesterday) but nothing was registered… so maybe it flew back to NYC? The bag contains my front door key, my wallet, etc. I had to sleep at my friends place the last days.
