 If you're a budget traveler, you're probably familiar with the airline's super-low fares, but first-time Frontier fliers might be wondering if there's a catch to those affordable tickets. Like most budget airlines, low fares often mean fewer inclusions, with extra costs for baggage, seat selection, and more. Of course, that low fare is worth the hassle of understanding the additional fees for some travelers, so the airline is breaking down the basics and checking out Frontier Airlines reviews to help you decide if it's the right airline for your next trip.

It's "America's greenest airline," as it has an average of 43% fuel savings compared to other American carriers. Plus, every airplane features an animal on its tail to bring awareness to these creatures and their environments.

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. 

In 2021, Frontier filed for an IPO.
