traveltips.wpengine.com interviews Travel Channel Host, Samantha Brown, as she answers the question of which is better: hard or soft-case luggage.
Brown explains that both suitcases have a place in the travel world, with pros and cons of each. First, she talks about soft-case luggage. Although it is very lightweight, there is no protection for your items. If you check a soft-case bag, your items inside will get knocked around and potentially damaged by the bigger, harder suitcases that are also being checked. Brown recommends using a soft-case suitcase if you plan on carrying on your luggage, but not to check it.
On the other hand, hard-case suitcases have the potential to be a lot heavier. However, suitcase manufacturers are starting to design hard suitcases that are extremely lightweight. The advantages of a hard suitcase is that it will protect the contents of your suitcase much better than a soft-case will. The disadvantages of hard-case luggage is it can be bulky. For that particular reason, Brown recommends using soft-case luggage strictly for carrying on, and a hard suitcase when checking your bag.
