I quit buying bottled water at airports and started packing an empty bottle for security
Used to drop $5 to $7 on a single bottle after every security line, which added up fast on a trip with layovers. Now I bring an empty Nalgene through TSA and fill it at a water fountain past the checkpoint, did it on a Denver to Seattle run last month and paid zero. The one catch is some airports moved their fountains or they come out warm. Where do you all refill on a long layover when the fountain situation is rough?
