Now we know who the real FTer is! :D

:p At the time I'm not sure I was even in any FF programs!

Anyway, since my flights were free (to me) I won't complain about the miles!

This obviously wasn't AA :)

Don't toy with me, French Teacher!

Well, they can, but they can't both earn miles for the flight.

My dad and I regularly used a joint PC account since we have the same name when we stayed in hotels. And for a while, he was earning miles on my AA flights (grrr) when he needed some extra miles. A few years after he passed away, I had his AA account merged with mine rather than pay the ridiculous fees to have the miles transferred from his account to mine.

Before I knew the rules a friend of mine tired to use my dads card. We were rapidly found out and my card was hole punched (south west airlines)

:D I only used "Michael Corbin" as an example...

Vive la France!

Let me point out the not so obvious
 

Given that I'm an identical twin - could I not use his/her passport or driver's license to get on a plane

Sure. But read "more common..." as meaning there are more father/son with the same names than identical twins.

If I were you, or your twin, I would select different airlines and hotels so you have more flexibility. :D

Note that I meant no offence to all identical twins out there!

could I get away with this?

I use FF miles to get a domestic roundtrip award ticket on Delta for 12 yo daughter.

a. 12yo flies to grandma's house (I accompany on the company's dime).

b. 2 weeks later, me, the wife, and 5yo daughter drive to grandma's house and stay for a couple of days. Then, we grab 12yo daughter, take her back home in the car, and leave 5yo daughter with grandma for two weeks.

c. 2 weeks later, I fly to grandma's for company business, then return with 5yo daughter on plane using 12yo daughter's RETURN ticket from roundtrip a. above.

Question: If the 12yo's name is on the ticket, can the 5yo use the return leg? No need for ID, right? Is this possible? Is it ethical/unethical?

Wow! Now I've seen everything.

You take a law school exam recently?

You would get away with it. Not ethical and illegal (theft of service), but I doubt you would get caught unless they had you verify the 12yo's age to make sure that she qualified for a special child's fare, and then on the return the same happened.

not necessarily: :D

Siblings who look enough like each other could simply use each other's ID's (the TSA or some other agency might cause problems if you're caught, though). I don't look really close to my sister, but drivers license pictures are so crummy - someone dyes their hair, gets a different hair cut, and adds glasses, and they look less like their own drivers license picture than I do to my sister's picture.
