Buying a day pass or booking through a lounge-access app is often cheaper than an equivalent airport meal once you factor in food, WiFi, and a quiet seat — worth pricing out even for economy passengers on a long layover.
Suvarnabhumi and Don Mueang are roughly an hour apart by road; if switching airports mid-trip, budget extra time for traffic and don't assume a quick taxi hop.
Day passes can usually be bought on arrival at the lounge desk, though pre-booking online occasionally offers a discount over the walk-up rate.
