Perhaps not that extreme, but I'm not aware of an inalienable right to fly on an airplane.How about a combination of you paid for a ticket and freedom of movement is a basic human right?
I'm not against reasonable and proportionate security, for air travel or anywhere else. But the kind of arguments some airports and airport security organisations have been making in recent years boil down to giving up all your legal rights to anything and not being guaranteed a service you've clearly paid for or even any sort of compensation if they deny you passage on some arbitrary grounds. (Sorry, one of our staff felt you raised your voice to them and we have a Zero Tolerance(TM) approach to that kind of thing -- look, it's right there on page 74 of the impractically long agreement you couldn't possibly have read before the web page timed out when you bought your ticket.)
If you'll pardon the pun, that kind of reasoning would never fly under normal legal conditions. Courts in almost any jurisdiction would throw out a contract where you paid for something but weren't guaranteed what you paid for or some sort of reasonable alternative or compensation if for good reasons it wasn't possible to provide it. And if it wasn't provided and not for a good reason, you would probably be entitled to compensation for any consequential losses as well. I don't see any reason that airports, airlines, or for that matter government-mandated security organisations, should be held to a lower standard, or not held to any standard at all, just because someone mentioned words like "air" or "travel".
