American Airlines flight 37, en route from Madrid, Spain, to Dallas Fort Worth International Airport on October 6, diverted to New York’s John F. Kennedy International Airport due to a malfunction affecting six of the aircraft's eight lavatories. The diversion was confirmed by an American Airlines spokesperson, who cited "an issue with the aircraft’s lavatories."
With only two restrooms operational for the transatlantic journey, the decision was made to divert to JFK. Air traffic control communications captured by LiveATC.net confirmed the pilot reported that only two lavatories remained functional.
The aircraft landed safely at JFK and underwent a maintenance inspection before continuing its journey to Dallas Fort Worth. "We never want to disrupt our customers’ travel plans and apologize for the inconvenience," an airline representative stated.
According to aviation expert and retired airline captain Steven Arroyo, the decision to divert was influenced by passenger comfort, hygiene, and potential safety concerns. Arroyo noted that long lines for the remaining restrooms could create security protocol issues and safety risks for passengers who might remain standing if the seat belt sign is activated.
For international flights, diverting to a gateway airport with customs and immigration services, such as JFK, is necessary for maintenance personnel to address such issues. Online discussions among travelers revealed shared experiences with restroom problems on flights, with some recounting instances of multiple lavatories becoming unusable or flights departing with no functioning bathrooms at all.
This incident follows other disruptions on US-bound flights. Notably, a British Airways flight from London to Chicago descended sharply and circled for hours before returning to London due to a technical issue.
