Major US Airline Hubs/Focus Cities

Good quiz man but I highly suggest changing how you accept answers and what answers you accept. Kind of annoying typing in a city and the name of the city pops up as a generalized whole indicating a single airport in that city, but then there’s 1-2 other airports in said city that have the name of the city plus one of the alternative airports the city hosts added to it that don’t pop up when entered in. Which you then have to use the specific airport name to guess the alternatives in those cities. Highly recommend either just accepting the name of the city as a whole and having all airports pop up when entered or making it so only the airport name is accepted. Makes it confusing on what to try to guess when you use a hybrid of both. Also it makes it pretty easy when all you have to type in is random 2-4 letter combos to finish 40% of the quiz.
