Airline rules regarding onboard photography are usually quite vague and often depend on the discretion of flight attendants. The TSA or the FAA do not have any rules restricting inflight camera use. However, partly due to security concerns and partly due to the risk of less-than-flattering images of in-flight food and plane interiors going public on blogs and social media, many airlines restrict passengers from taking photos of aircraft interiors, meals or their staff.
Most major airlines – including American Airlines, United, Delta, Southwest and JetBlue – recommend that passengers should only take photos/videos of their personal events and for personal use only.
