Hi i am travelling to Nepal after 17 years. Dunno if i will come back or not. I have no plan to stay abroad. But if my mind changes, i will. Staying away from family has killed me indirectly. What are the baggage limits? Can i travel with tsa lock suitcase? What is the dimension of suitcase needs to be? How big suitcase or luggage can be? How much weight? Will our luggage go directly to Nepal or will it first go to Doha as I have to travel through Doha transit
