The Federal Aviation Administration jumped into the heated dispute over gates at the new Love Field terminal, launching an investigation into whether Delta Airlines has been treated fairly according to federal rules.
Delta’s deal expires next month and the Atlanta-based carrier could be forced to shut down its operations at the city-owned airport.
In a “notice of investigation” letter sent to the city on Monday, the FAA warned the city could lose federal money if it is determined the city violated provisions of any grants.
The agency awarded Love Field $149 million from 1985-2013.
The FAA also asked the city to continue allowing Delta Airlines to operate at Love Field until the investigation is complete, which could be months.
The controversy has already landed the city and the two airlines in federal court.
Southwest declined to comment Monday, while Delta and the city of Dallas have not returned inquiries for comment.
