Do I feel lucky? In what respect?

That the AA's passport scanners (which wouldn't scan my passport) are as good as the Border agent's scanners that did scan my passport?

That the AA agent knows how to operate the machinery properly or that its been serviced?

If AA is going to deny people boarding because they can't scan their passports they need to explain why upon re-entering the country my passport scanned fine.

Also, just to clarify, my passport looks fine, it just doesn't scan.
