When I travel on holidays, I almost always carry only a cabin luggage. I find my trusted backpack provides me with greater mobility and flexibility than having to carry a suitcase. Also, having only a carry-on luggage mean zero chances of lost luggage on long-haul flights and also eliminates waiting for luggage at the conveyor belt upon arrival.
With all its perks, carrying only a cabin luggage comes with certain restrictions. Before you decide to pack your luggage for carry-on, I strongly recommend you read the TSA guidelines from the airport/airlines' website.
In this post, I shall share with you how I pack liquids in my carry-on luggage.
