BOSTON- Frontier Airlines (F9) has filed a second federal lawsuit against American Airlines (AA) over a ground collision at Boston Logan International Airport (BOS) that damaged a parked Frontier Airbus A321 aircraft.
The incident, which occurred on November 25, 2024, forced the aircraft out of service for six days and resulted in total repair costs exceeding $670,000.
The lawsuit, lodged in a Massachusetts district court, demands American Airlines (AA) pay the outstanding balance of the repair bill along with additional damages for lost revenue and operational disruption.
This legal action follows a separate lawsuit Frontier Airlines (F9) filed against American Airlines (AA) over a similar ground collision at Miami International Airport (MIA) earlier in 2024.

Frontier Sues American Airlines Over Collision
According to the complaint reviewed by PYOK, the Frontier Airlines Airbus A321 was correctly parked at Gate E14A at Boston Logan International Airport on November 25, 2024. The aircraft was fully boarded with passengers and awaiting pushback for departure.
Before the Frontier aircraft could begin its pushback, an arriving American Airlines plane needed to park at the adjacent Gate E13. As the American Airlines aircraft turned into its parking position, its wing struck the wing and aerodynamic sharklet of the stationary Frontier plane.
The impact forced Frontier to immediately remove the aircraft from service. The airline cancelled the scheduled flight and dispatched engineers to assess the damage. Their inspection revealed extensive structural damage that required six full days of repairs before the aircraft could return to operations.
Frontier’s legal team stated the total cost of repairs reached $670,387.45. The airline is now pursuing American Airlines for the unpaid portion of that bill, along with compensation for the broader financial impact of losing an aircraft for nearly a week.

American Airlines Covered Only Half the Repair Bill
Nearly a year after the collision, in September 2025, American Airlines agreed to pay 50% of the total repair cost.
Frontier accepted this partial payment of approximately $335,193.72 but explicitly reserved its right to recover the remaining costs and additional damages at a later date.
Frontier is now exercising that right. The lawsuit demands American Airlines pay the outstanding $335,193.73, plus what the complaint describes as substantial damages for lost profits and operational costs caused by the aircraft’s grounding.

Second Collision Lawsuit Highlights Safety Concerns
This Boston Logan case is the second time Frontier has taken American Airlines to court over a ground collision in recent months.
In a separate lawsuit filed in a Florida court, Frontier demanded more than $100,000 in damages for a collision at Miami International Airport in March 2024. That incident grounded the affected Frontier aircraft for approximately six months.
Both lawsuits raise pointed concerns about safety standards at American Airlines. The legal filings state that these incidents placed American Airlines on notice of systemic deficiencies in its safety practices, training, supervision, and compliance protocols.
Frontier’s attorneys argue that American Airlines failed to implement corrective measures despite being aware of these issues.
The earlier Miami International Airport case is scheduled for mediation as both parties attempt to reach a settlement outside of court.
The outcome of these cases could set a precedent for how airlines resolve disputes over ground handling incidents and the financial responsibilities that follow aircraft damage during airport operations.
