The ONLY answer to this security threat is for EVERY airline passenger to be cryogenically frozen prior to take-off, then thawed on arrival.
It’s a win-win for evryone. The airlines can make more money because they can stack passengers in the planes like cord-wood. They’ll also need fewer flight attendants.
And the passengers don’t have to worry about getting “blowed up” by some wacko during their flight.

Humor is good, thank you.
