It's a list that has names of people who are on the terrorist watch list; are wanted by police/FBI, etc.; or have been blacklisted for attacking cabin crew or disobeying cabin crew requirements, either during the pandemic or at any time prior to or after same.

Being "blacklisted" by an airline means you have been placed on that specific carrier's internal no-fly list, usually as a result of unruly conduct or serious safety violations. Unlike the federal "No-Fly List" (managed by the government for security/terrorism risks), an airline blacklist is a private business decision. Common reasons for being banned in 2026 include verbal or physical abuse of crew, refusing to follow safety instructions, smoking on board, or extreme intoxication. The consequences are severe: you will be unable to book any future flights with that airline or its regional subsidiaries. As of early 2026, being banned by one airline does not automatically prevent you from flying with another, but there is an ongoing industry push to share these lists across carriers to enhance safety. Once blacklisted, the decision is rarely reversed; you would have to file a formal appeal with the airline's customer service or legal department, a process that can take months and often requires proof of a significant "change in behavior" or a medical explanation. Ultimately, it is a "scarlet letter" in the travel world that significantly limits your flight options.
