While walking towards the boarding gate for EK-504 in Lounge C-19 on 06-Aug-2014 ( Wednesday ) travelling " Lagos - Dubai - Mumbai " my dark blue Benetton Blazer slipped out of the Computer Bag handle. This went unnoticed by me. Later when disembarking in Mumbai I realized my Blazer was missing. I informed the EK representative on ground when collecting the checked-in baggage..She advised me to report the loss on-line.I would appreciate your response ASAP. My e-mail is " [email protected] ". I was seated in 45-A. Regards - Capt.MK Roy.
