But it can end badly.
"American Airlines’ policy, states:
And.
"A different scenario, and the kind the airline is concerned about, might be you recording an argument with a counter agent or flight attendant for the purpose of filing a dispute or legal claim. Although personal to some, this interaction is likely to fall under the “do not record per the conditions” section of your agreement. Should you continue to record, the airline agent would be within the agreed-upon bounds to deny you the benefit of travel. Even though this display might be public, you have still agreed to the terms of your particular contract and should not be shocked when those terms are enforced. An onlooker recording the same interaction would be subject to the terms only if he or she was a passenger of that particular airline.
While it may seem unfair, the airlines can and do enforce these terms. It should not come as a surprise when a public relations fiasco puts the airlines on alert to protect themselves, their employees and their passengers."
This article seeks to answer the difficult question that many passengers have, “What can you legally film on airplanes and in airport?”
