MEMO TO BRITISH AIRWAYS Combing through the meal selections of customers probably isn't the most sophisticated way to catch terrorists.

But if flagging "Muslim meal" ticket holders for closer scrutiny is going to be part of your security regimen, you might want to avoid sharing that fact with flagged customers.

And you probably also want to avoid apologizing to these customers for the inconvenience they endure. It doesn't make you look good--especially if the apology intimates: Sorry for the bother. I mean, you don't even look like a terrorist.

Just a thought.
