I am writing this letter to report the loss of my cabin bag on the airline. My flight was on 21st April from New York to Paris at 8:00AM. The flight number was A222 and my Seat Number was B68. The last time I saw my suitcase was while placing it on the top of my seat in the aisle. After that, I forgot to take that out and checked out without taking it out. I didn’t even realize until I reached home, which was too late to contact the cabin crew.
