I have three examples of why you might want to just let it sit and see what the airline does in say, 4-6 weeks... Some might call this no good, but some may say it is best to take what you can get when it comes to you! Doing nothing is certainly not wrong here! Do THEY KNOW you even checked your statement?

just a thought, but here are my similar experiences...

1) Once I used Lending Tree once and signed on for 10k FF miles when getting my loan set up for a condo. I later switched lenders because the one I got assigned to me was actually no good and later I felt like I was being a bit taken by them anyway. I got a new lender and the new loan. Did not care at the time so much about the miles... I ended up getting the 10k posted anyway even though I never expected it. I also never looked into whether the new lender (not found using LendingTree.com) was affiliated or not and it is likely they were not. I have nothing bad to say about LendingTree.com but nothing good either... That is up to you all. FOr me, it did no good. BUT I did not press the issue on my newly added miles, nor did I do much of anything regarding my FF acct and they have remained in their for more than 1 year... I actually just reached 25k award level and may use it some day. If not, well, that acct was low anyway so whatever. I have other miles in the programs I like better anyhow.

Should I tell the airline? I dunno. In my case, no. They make so many mistakes, cant find some of their own marketing promos, and have links to bogus, no-longer-in-use sites or deals, I guess one hand kind of washes the other. It has also happened to me a few times that, using MCI partners for example, I got extra miles or got credits back on the LD useage but was even told that the miles could probably stay in my FF accts.

2) I once got a ticket refund of a $200 check from AA and then I got it again in the mail the next week! So, TWICE--a CHECK from the same problem! I called them to tell them about this and the CS lady there put me on hold and came back and said, and I quote: "Thank you sir for bringing this to our attention and being honest. Due to that, and the fact that it is actually harder for us to put the money back into our systems, you may keep it!" I did, of course. I was living overseas at the time and had already put a lot into mailings, faxings, copies and LD calls anyway.

3) Years ago, in college, a friend of mine saw someone trying to rob the pizza man when he was delivering some large pies to our dorm. My friend wanted to help out and so he called the police on the guy who got caught. The police thanked my friend but then, EVERY TIME something happened in that dorm, the cops would call my friend and sometimes, if there was a similiar prank or crime, they would put HIM on the suspect list and he would get woken up or bothered all the time! So much for sneaking beers on campus for him after that! Of course, this is not normal, but when you are in college and you like fun (not steeling) you kinda dont want to know or deal with the police...) The example, however, shows that sometimes, once you open your mouth, you are now on the spot a lot more anyway!


My advise would be to do nothing for the while. Maybe they will go away on their own. If this was money, and this was about your bank or your employer, I would totally tell them and give it back. And these days, being no longer in school, I would also tell cops if I saw a crime but I am certainly no tattle-tale! These are miles. They have only a value to you when you can actually use them and by gosh, that's hard enough to do! Reap and fly, my friend! Let us know some day though what took place.
