Answer 1

TRAVEL BAG IS MOST COMMON BECAUSE IT IS VERY USEFUL FOR CARRYING THINGS LIKE CLOTHES,FOOD,LAPTOPS ,ETC  NOT ONLY FOR TRAVELLING FOR A LONG ROUTE BUT FOR SHORT ALSO . ITS IMPORTANT BECAUSE YOU CANT JUST TAKE YOUR TEA BAG OR SLEEPING BAG FOR YOUR JOURNEY . TEA BAG IS NOT SO COMMON IN INDIA BECAUSE ALL INDIANS OR SOME PREFER TO DRINK TEA WHICH THE SERVORS  GIVE IN TRAINS OR AEROPLANES .SLEEPING BAG CAN BE IMPORTANT FOR TRAIN AND IN TRAIN NOT FOR AC ROOMS BECAUSE THE PASSENGERS GET SLEEPING BAG FROM THE COMPARTMENT.

Travel bag is your answer.
