Haha! Okay. Well, don't tell her how old the plane is. Anyhow, by the time you find out what the tail number is you're likely at your destination. Yes, the winglets are indeed sharp. Seriously though, a planes age is not measured in years, but in cycles. I guarantee HAL wouldn't be flying a plane that was unsafe due to age. But I understand the concern.
yes, I have never flown a 767 with winglets, and yet, I've flown the 767 many times (DL, AA, LY).
I know HA is a safe airline that wouldn't take risks, but I still feel safer on newer planes
