A good carry-on bag that is not too big to fit in the overhead rack but can also store all the essential items you'll need during the flight like your handheld electronic devices, a book or magazine to read, tickets, visa, a small snack and a jacket if you're travelling somewhere cold is the next thing you'll want to consider. If you're travelling to several destinations or planned several activities this bag will come in handy as you can carry it around while leaving your luggage at the hotel or resort that you're staying at. You may want to consider using a travel document organiser to store your passport, visa, ID, credit cards, boarding pass and a pen to save you the time of digging through your carry-on to find them in a rush.
