Interesting question!No, this is not illegal insider trading:
U.S. SECURITIES AND EXCHANGE COMMISSION - Insider Trading
Illegal insider trading refers generally to buying orselling a security, in breach of a fiduciary duty or otherrelationship of trust and confidence, on the basis of material,nonpublic information about the security. Insider trading violationsmay also include "tipping" such information, securities trading by theperson "tipped," and securities trading by those who misappropriatesuch information.
As an ordinary passenger, you have no fiduciary duty or other relationship of trust and confidence to Boeing, so illegal insider trading isn't applicable to this case. (Unless there is something obscure in the fine print on an airline ticket, somehow burdening you with fiduciary responsibility.)
