As the reality of the ISIS bombing of a Russian jetliner over Sinai and the most recent events in Paris settle in, stress on-board will get much worse.

Expect more incidents like the ones in recent days, where any perceived irregularity, sets people off. Several flights to/from Paris have already been diverted due to unfounded "security concerns".

This will all be exacerbated by increased security hassles in airports, where it has been reported that the TSA can still not locate more than 25% of prohibited items.

The best hope is that the illusion of aviation security persists, and the traveling public continues to buy it.
