What packing strategies help avoid extra baggage fees?

Airline baggage fees can add up quickly, especially if you're traveling with multiple bags or heavier luggage.

Over time I’ve tried different approaches to stay within airline limits. Packing lighter fabrics helps, and rolling clothes definitely saves a little space. But bulky clothing, especially winter layers, can still fill a suitcase faster than expected.

I’ve also seen some travelers experiment with vacuum compression bags designed for travel instead of home storage. The idea seems to be removing trapped air from clothing so it takes up less space in luggage.

I’m curious what works best for people who travel on a budget.

Do you rely on packing cubes, compression bags, minimalist packing, or something else to avoid paying extra baggage fees?
