Work out how much leisure time a layover leaves after processing.
Subtracting the processing time to get into the terminal and the boarding window from the layover leaves the true free time. That remainder decides whether a lounge visit is worthwhile. A layover that looks long on paper can evaporate once processing and boarding are removed, so computing free time protects your lounge budget and gate timing.
