Which airlines ban the use of Knee Defenders during flight?

Question

I read that some airlines such as United Airlines ban the use of Knee Defenders during flight. Is there any comprehensive list of airlines that ban the use of Knee Defenders during flight (or conversely a list of airlines that do not ban them)?

Answer 1

Such a list would not be meaningful. All airlines have wide rules to prohibit "tampering" with seats, with Knee Defenders or otherwise; you can improvise one with a well-sized bottle, after all. Those that point out the Knee Defender as banned are only making it explicit that this specific device is not allowed.

More to the point, if the passenger unable to recline complains, the flight attendants will insist that you stop using it.

Answer 2

It would appear not, but there's nothing stopping us from creating one. People can edit the answer as we find more.
