If we are speaking generally, for example, on a day-to-day basis, for example, you could say that
'I like travelling light.' This phrase could also be applied to the case where people are travelling by bus, train or plane and prefer not to take large suitcases. These days, with low cost air travel, the cost of hold luggage is quite expensive so many passengers prefer not to be laden with heavy baggage for financial reasons.
"Shall we take a suitcase on our holiday, or just cabin luggage?"
"Let's travel light and just take take carry-on bags."
Carry-on bags = The term cabin baggage or carry-on in baggage refers to the type of luggage that passengers are allowed to carry along in the passenger compartment of a plane rather than the cargo compartment.
一般的な日常会話では'I like travelling light.'
（身軽な旅行が好きです）のような表現ができるでしょう。
