Airports are some of the most miserable places on earth. On top of being charged way too much for food and booze, solid internet connections can be dodgy whether you're connecting to provided WiFi or your cellular network. The folks at Speedtest have done us all a favor and surveyed the offerings at North American airports to suss out the worst to the... surprisingly not-worst. Interestingly enough, a state that legalized recreational marijuana also has the highest uploads and downloads. Denver International boasts 78.22 Mbps downloads and 78.29 Mbps on average, with Speedtest reporting that this actually increased by over 25 percent since its last look.
