The packing mistake that costs more than the bag fee it's trying to avoid

Travelers overpack to avoid a checked-bag fee, then spend more in lost time — waiting at baggage claim, lugging an overweight carry-on through terminals — than the fee itself would have cost, and I did this for years before actually running the math.

A checked bag costs a fixed fee and frees both hands and a huge amount of decision fatigue at security and boarding. An overstuffed carry-on costs invisible time: extra minutes at security, exhaustion moving between gates, and the mental tax of guarding it the entire trip.

My actual rule now: if the carry-on requires real effort to close, it's cheaper in every way that matters to just check a bag and walk through the airport with my hands free.
