In April, a JetBlue Airways crew called airport police to meet a man who they said continued to record a selfie video during a security-sensitive time in flight, while the cockpit door was opened. With airline customer service in decline, videotaping is the only way that passengers can make sure they are treated fairly, says Gary Leff, a travel blogger who has criticized the airlines over the issue. The Transportation Security Administration says that photography at checkpoints is fine if people don't take images of monitors or interfere with screeners. Lawyers who specialize in First Amendment or travel law say airlines generally cannot limit photography or video recording in an airport because it is a public space. [...] there is no law against taking photos or video on a plane, and it is unlikely that anyone would face legal jeopardy for taking pictures of an altercation on a plane or their own peaceful dispute with an airline employee, Larsen says. After a video of a confrontation over a stroller between an American Airlines flight attendant and a mother with two young children, the airline grounded the employee.
