Assume you are taking an airline flight, and the cabin starts filling up with smoke. The pilots divert the plane to the nearest suitable airport, and the flight attendants pop the doors and send you down the slides as soon as the airplane comes to a stop and the engines shut down. However, by the time firefighters can check the interior of the aircraft out, no smoke, fumes, or heat sources can be found.
How would the airline get your carryon/hand luggage back to you under the circumstances, and when should you expect it back? I presume that this varies from airline to airline, but representative answers are appreciated.
