A lounge day pass typically costs thirty to sixty dollars, so the question is whether the food, drinks, Wi-Fi, and comfort add up to that much for your specific trip.

The break-even math is simple: compare the pass price with what you would actually spend in the terminal on a meal, drinks, and Wi-Fi. On a long layover it often breaks even.

Day passes are best value on layovers of three hours or more, overnight delays, or when you need to work or shower before a long flight.

Before paying, check whether your credit card, ticket class, or frequent flyer status already includes lounge access, since many travellers already have it without realising.
