Training and awareness are not plans. Reacting to situtations when they happen is not a plan. Nor is it deviation from a plan.

Here, I'll give you three plans nevertheless:

1. I would have gotten up from my seat, run to the back and projectile vomited over as many of the conspirators as possible.
2. I would have reseated myself or trekked over to the most blatant of the Syrians and said in a loud voice -- "What the heck are you guys doing? Making bombs in the bathroom? You've got half the plane terrified, did you know that? Going to the potty in sync, carrying a bag and coming out bagless ... what the heck ar you guys doing!"
3. I would have walked back to the head when they all did and nudged and bumped them alll accidental like, and then glared madly at them.

You still can't come up with a plan. Until you do, you would look less foolish to avoid the question.
