In the first two decades of the 21st century, low-cost airlines in the United States began to rise to prominence, capturing significant portions of the market by undercutting legacy airlines on ticket prices and opening up travel to an entirely new demographic. With $50 fares from the Northeast to Florida courtesy of Spirit Airlines and JetBlue, Americans began to travel more than ever, making regular trips between cities to visit friends and relatives while also flying for more and more vacations than ever before.
