Frontier Sues American for $100,000 Over 2024’s Jet Damage

Frontier Airlines has taken legal action against American Airlines, filing a federal lawsuit in the US District Court for the Southern District of Florida.

The low-cost carrier accuses American of negligence in relation to a runway-adjacent ground accident that took place on March 7, 2024, at Miami International Airport. Frontier is seeking more than $100,000 in damages, arguing that the financial consequences of the incident extend well beyond the physical repairs that were already partly addressed in a prior settlement.

How the aircraft damage occurred

According to the complaint, the accident happened during a pushback maneuver involving an American Airlines Boeing 777-300ER that was preparing to depart Miami for São Paulo/Guarulhos–Governor André Franco Montoro International Airport (GRU). The widebody jet was positioned in what was described as a tight parking corridor, with aircraft stationed on both sides.

At the same time, a Frontier Airbus A321neo was parked at a nearby gate and was subject to a ground delay program, meaning it remained stationary during the sequence of events.

Frontier alleges that, during pushback, the American aircraft failed to maintain the required safety clearance buffer. As a result, the Boeing 777’s movement brought it into contact with the vertical stabilizer, the tail fin structure, of the Frontier A321neo.

The impact caused serious structural damage, particularly to the stabilizer, which required detailed inspections and engineering evaluations before repairs could begin.

Operational and financial fallout for Frontier

Because of the severity of the damage, Frontier states that the aircraft had to be withdrawn from service for roughly six months while the vertical stabilizer was replaced. The extended grounding created a chain of operational challenges.

Frontier further claims that, even though some repair costs were covered in an earlier agreement, the airline continues to bear indirect financial losses. These include ongoing lease payments for an aircraft that could not operate, missed revenue opportunities, and lost profits tied to the prolonged absence of the jet from active service. The lawsuit argues that these consequential damages remain unpaid.

Allegations of non-compliant ground handling

Central to Frontier’s legal argument is the claim that the pushback operation conducted by American Airlines personnel did not comply with established ground safety procedures. The carrier asserts that the maneuver was handled “out of compliance,” suggesting that required spacing rules and operational safeguards were not properly observed at the time of the incident.

Claims of broader safety concerns

Frontier’s complaint also references another ground-handling event involving American Airlines.

In November 2024 at Boston Logan International Airport, Frontier says a separate pushback incident involving American similarly resulted in damage to one of its aircraft. Frontier argues that these cases point to deeper, systemic shortcomings in American’s ramp safety culture, training standards, and procedural compliance. The airline contends that such risks should have been identified and mitigated before the Miami collision took place.

A month ago, Frontier Group appointed James G. Dempsey as permanent President and CEO, adding him to the board of directors. Dempsey had served as interim CEO since mid-December 2025, following the abrupt departure of former CEO Barry Biffle.
