How to Pack: Travel Smart for Any Trip by Hitha Palepu is an applicable book about the art of packing for flight. Things I especially like about the book are the section on pre-packing (which details how to pack on each of the seven days before departure and the morning of the flight), as well as items you do and do not want to be checked into your suitcase. The book also talks about ideal clothes to pack when packing lightly (though, realistically, most people don’t have the luxury of choosing the perfect clothes to fit their suitcase – they have affordable clothes that fit them and need to be packed). Palepu is very thorough, and she gives a lot of tips and advice on how to pack efficiently and fly easily.
