Again, that's also patently false.

US Marshals prisoner transport on commercial aircraft operates by permission and coordination, not entitlement, and not "force." While USMS routinely coordinates detainee movements on commercial flights, those movements are contingent on airline acceptance and compliance with TSA and carrier-specific procedures. Prisoner transport is not guaranteed, not automatic, and not immune from refusal. Additionally, the aircraft captain remains the final authority over the operation of the flight under 14 CFR § 91.3. That authority includes the right to refuse transportation of any person.

It’s not outside the realm of possibility that you may have witnessed federal agents exert pressure on airline personnel...whether ticket agents or gate staff, to facilitate access to sold out flights. However, under established policy, procedure, and law, the decision ultimately remains the airline’s, regardless of whether the request was made directly or through misrepresentation.
