Here's a guide to how much legroom you get on America's airlines

As airlines around the world search for higher revenues and increased profitability, the effect on the passenger experience has not been overly positive, to say the least. Even though airliners have not been getting any larger, their passenger carrying capacity has been growing steadily. Airlines have achieved this by cutting down the size of lavatories and the amount room between seats. (This is also known as seat pitch.)

Using data from TripAdvisor's SeatGuru as well as from airlines themselves, we've compiled a rundown of the amount of seat pitch offered in the economy-class cabins of America's major airlines. This includes the nation's three major legacy carriers along with boutique airlines such as JetBlue and Virgin America, as well as ultra-low-cost operators such as Spirit and Frontier.
