A new U.S. Senate Commerce Committee report says federal officials pressed Logan International Airport in Boston to house migrants during the height of Massachusetts’s shelter emergency two years ago, despite warnings from airport leaders that the move would compromise security and disrupt operations.

The report, titled Flight Risk, describes several ways the Republican-led committee believes the Biden administration weakened aviation security nationwide. Logan is one of three major airports highlighted in the findings, along with John F. Kennedy International Airport in New York and O’Hare International Airport in Chicago.

The White House and the Federal Aviation Administration asked Logan and other major airports to identify space where newly arrived migrants could sleep overnight, the report said. The Massachusetts Port Authority, which operates Logan, warned federal officials that the airport lacked the facilities to act as an intake site and said using terminals for that purpose would pose “security and operational risks.”

Despite those warnings, the report says, the Federal Aviation Administration and Democratic state and local officials overruled Massport and allowed migrants to stay overnight in parts of Terminal E, which serves mostly international flights. The practice began in July 2023 and continued for about a year while the state’s shelter system exceeded capacity. The state stopped using Logan Airport to house migrants on July 9, 2024.

The committee noted that Logan receives Federal Aviation Administration grants, meaning its facilities are supposed to remain available for aviation-related use. Investigators wrote that the airport’s temporary role as an overflow shelter conflicted with that obligation.

The report also describes how migrants flew into U.S. airports through new federal parole programs and the CBP One mobile application, which was created by U.S. Customs and Border Patrol. From October 2022 through May 2024, more than 460,000 migrants were permitted to enter the country via commercial airports under these programs, including arrivals at Logan.

Committee investigators said the federal Transportation Security Administration relied on inconsistent or incomplete data from the CBP One app to verify identities. It cited a November 2023 case where the Transportation Security Administration processed more than 1,700 travelers in a single day without identification. The agency later updated its procedures to require biometric photos after the committee raised concerns.

The report also criticizes the Biden administration for diverting federal air marshals from flights to assist with the border situation. The committee said the move left fewer marshals available to protect the flying public.

Massport has previously said Logan was used as an emergency location only because the state’s shelter system had reached capacity. Migrants were placed in an unused public area of Terminal E overnight and then transported to state-run welcome centers in the morning. Airport officials said Logan did not provide services to the individuals staying there.

Massachusetts is the only state in the country with a right-to-shelter law, which requires the state to provide emergency housing to eligible homeless families with children and pregnant women. The statute has no residency requirement, meaning newly arrived migrants — which in Boston were primarily from Haiti — qualify the same way as long-time Massachusetts residents, which contributed to the system exceeding capacity in 2023 and 2024.

The committee report describes communication among Massport, the Federal Aviation Administration, and state officials as the situation continued. At one point, Massport asked federal regulators for guidance on how to handle requests to house additional migrants at Logan.

Massport could not be reached for comment on Tuesday or Wednesday. Nor could a spokesman for Massachusetts Governor Maura Healey.
