The eighth-largest commercial airline in the US, Frontier Airlines operates flights to over 100 destinations throughout the United States and 30 international destinations, and employs more than 3,000 staff. The carrier is a subsidiary and operating brand of Indigo Partners, LLC, and maintains a hub at Denver International Airport with numerous focus cities across the US.
  In 2020, class-action lawsuits against Frontier were filed after the company refused to refund airfare for customers who could not travel during the COVID-19 pandemic. The company accepted part of the $25 billion in U.S. government funds to offset financial damage to the airline industry during the outbreak.
