Low Fares, High Stakes: Breaking Down Spirit Airlines’ Closure

What happens when a major ultra-low-cost airline shuts down? In this episode of The Runway Up, the team sits down with aviation industry analyst Bill Swelbar and Metropolitan Knoxville Airport Authority Vice President of Air Service & Marketing Jim Evans to unpack the closure of Spirit Airlines and what it means for travelers, airports, and the future of affordable air travel. Although Spirit never served McGhee Tyson Airport, its shutdown is sending ripples across the aviation industry. Bill and Jim discuss why Spirit’s collapse was years in the making, how other airlines are already filling the gaps, and what separates successful low-cost carriers like Allegiant from struggling competitors. The conversation also explores Knoxville’s growing aviation market, why airlines are paying attention to East Tennessee, the evolving role of competition in airfare pricing, and what travelers can expect from future airline growth. Plus: TikTok-fueled efforts to revive Spirit Airlines, the realities of airline profit margins, and why running an airline is far harder than most people realize.
