just popped into my head

I was wondering if identical twins ever abused a ff program. If I had an identical twin, I certainly would try it!

How exactly would that work? If you were a twin, would you use your twin's passport and commit who knows what federal offense, just for the sake of maximizing miles in one account?

If twins travel together, it sort of defeats the attempt.

Don't need a passport to travel domestically.

don't forget father & son who have the same name.
Example: Michael Corbin and Michael Corbin, Jr. However,
both of them have the exact same name on their frequent
flyer accounts.(just "Michael Corbin")

The above names are made up, of course. However, they
have never had a problem with most US airlines. However,
they sort of got busted once when the son was checking
in for a Singapore Airlines flight. The check-in agent said
"sir, there's a problem with you membership number, you
are not that old..." fortunately, the line was long, so the
SQ agent told him to contact SQ member service on the
phone when he gets back...

Obviously the son flies a lot more than the father, but the
father also does quite a bit of leisure flying.

I know a father and son with the same name that share FF numbers. As a result the are top tier on an airline. The only challenge is that they can never travel together. I'm actually surprised the airline never realized this since they often have trips to the same location a day apart or to different locations on the same day!

it probably depends on the airline's software.

A few years ago, I did a mileage run in one day. 3 LGA-BOS shuttle flights all in one day. A few days later, I noticed my online acct status had been locked out. I called customer service and was told their system was alerted to a possible abuse/fraud. It turned out that some of the 3 identical LGA-BOS roundtrips set it off.(the last BOS-LGA was credited TWICE) It resulted in an audit of my acct. Fortunately, the agent cleared it up pretty quickly.

I work for a Sr. who often buys plane tickets for Jr. God, it's confusing, especially since they're both F. Middle Name. It's hard enough to get Web sites to acknowledge the "F" as the real first name and they both go by "Middle", but trying to add the Jr. or Sr. is just totally confusing.

As a twin, I have earned miles for flights my sibling took. And we're not identical, or even of the same sex!

Correct me if I'm wrong, but couldn't you earn miles for someone not even related to you? Airline T&C's usually state something to the effect that Photo ID is not required to fly, although it may subject you to additional security screening.

Okay, I will admit it. I am a III. My father is a Jr. I have used his non refundable tickets before

It is difficult sometimes to book flights when we fly together. I have gotten calls where they have cancelled the duplicate booking for me as a favor...

I've thought about it with my twin but he's an arsehole

We have the same initials so I don't think it would be picked up anywhere

Most twins do not have the same names. Probably more common with father/son Jr. types.

If you can I guess you could use a first and second initial only if they matched.

My imagination is running wild. I would like to see a movie about twins who deceive an airline. I propose Jeremy Irons for both roles.

About 12 years ago my parents had a scheduled 3-week trip to Italy and France. It turned out my dad had some work stuff come up and couldn't go. We have the same name (not middle initial, but don't use them). I travelled in his place (He got the miles)

Same idea, but with hotels: - more than once I've had points show up in my accounts when my parents stayed somewhere and didn't confirm the correct frequent guest number.
