There are several different variables that determine the price you pay for a flight, including how far in advance you book, the day of the week you fly, and the airport you’re flying into or out of. The airline you fly also will have an impact, depending on whether there is a budget airline available to you and whether or not your local airport is an airline hub.

To determine the cheapest airline for domestic flights in every state, CashNetUSA created flight route combinations from each official U.S. hub airport to all the others. (Note that Delaware was excluded because it has no hub airport.) Next, it collected a sample of one-way flights for each route, with no more than one stop. Finally, CashNetUSA calculated the average price per mile for each airline across all routes for each airport and the average for each state.
Based on this analysis, this is the cheapest airline in every state for domestic travel.
