For decades, the Office of Refugee Resettlement (ORR) has had a national network of shelters for migrant children who arrive at the border. If a child arrives at the border and the only space available is a shelter far from the border, ORR will put the child on a plane rather than a multi-day bus trip. Rather than being a conspiracy, the flights are simply normal practice for ORR across multiple administrations. The shelter in Westchester has been there for years and there are even videos from 2018 of similar flights carrying migrant children into the New York area.
In recent years, ORR has also sometimes helped transport children to their family members after they get sponsored out of government custody. This common-sense measure has allowed children to get into the arms of a loved one faster than if the parent drove across the country to come pick them up. In all those cases, the child has a right to remain in the United States while they go through the court process. The government agency is simply smoothing out the process for them.
Similar situations with adult migrants have also occurred for years. U.S. Immigration and Customs Enforcement (ICE) often chooses to release some percent of people at the border or from a detention center on bond or an “alternatives to detention” program such as electronic monitoring.
If the person is being released far from their ultimate destination, then ICE will make sure the person’s sponsor (usually a family member) has bought them a plane or bus ticket so they can get to their destination in safety]. Under both Obama and Trump, it was routine to see migrants being dropped off at the San Antonio bus station with Greyhound tickets. Even in 2019, during the height of Trump’s anti-asylum policies, ICE was contracting with private companies to drop migrants off at shelters.
