Several of the other FF program numbering systems have produced curiosities. I just noticed the Delta thread today, and recall an entertaining AAdvantage one from The Other Place. The DM numbers have undergone major structural changes. Mine is 7A4D### while Mrs. jb, opened in 2010 has eleven numbers beginning 4006. I have no idea at all when I opened mine but it must have been fairly early in the Agony Airlines days.
And with AAdvantage all you need to do is sign in to get your signup date, for me: Member Since: Thursday, October 29, 1981
Old 7-digit US Airways #, I don't think I signed up until 1997 or so. Really the 7 digit #s have leading 0s, though, right, to correspond to the same # of digits as the old America West FlightFund #s?
Both of us have the DM# which is the mix of numbers and letters: NLNNNLN. I can't remember if our are surviving American West numbers. Mid 90s sign up, probably. The kids have 11-digit ones, all numerical
My DM number begins with 998 and is 7 digits all numbers. My old US Air number began with 720 (the 7 was added later so it really was 20). My AA number is E33 all numbers thereafter.
I'm relatively new to Dividend Miles - 11 digits beginning with 400. On my membership card - it states when i joined - a sad "since 2009". (I've been a Mileage Plus member since the late 80s flying between Canada and Asia - and that's where most of my US flying went.)
It's some stupid number - in the extremely rare cases where I must fly US, I credit my UA account, which I can rattle off by heart. I do wish someone (AA?) would kill that airline.
Mine is the 'old configuration' consisting of numbers and letters. +1 is the same - mine opened in '96 - his opened in 2000.
8##B0XX something like that. I joined the Piedmont Frequent Flyer program in 1987..... I was 17. When US came along, they put a 7 in front of my original PI number and that was that until US cutover to Sabre....or at least that's when I recall the next rendition of a US DM # came along. My AA # is 3 letters followed by 4 numbers....7 digits total.....like my US number was. I assumed it's a Sabre thing. Doesn't matter now that US is out of Sabre, and like gleff said, I think my official US # is preceeded by a bunch of zeroes to match the numbering convention of the new US and they just let me use the last 7 digits as my old #.
My vintage DM# starts with "000"... I got it in 1987 when I joined America West "FlightFund". Interestingly, I've found I need to enter the leading zeroes in order for certain processes to work properly. Usually leading zeroes can be dropped... not in this case!
Mine is 7 digits and a mix of numbers and letters...which is interesting because I think I joined in 2003, which seems much later than many others with this "old school" configuration.
Mine is also 7 digits and a mix of numbers and letters - Been a member since 1988 when I was 7 yrs old!!
7 digits, alpha numerical. At one point I had 2 accounts (possibly one was an old PI account) but eventually the accounts were combined. Member since 1987.
All numbers, beginning with 3000. It was an HP number. Had a US acct at some point, but the account went dormant and was probably closed.
I'm actually thinking about asking US to give me a new number. I like my little 7 character alpha-numeric number, but United gives me hell every time I fly them...even though I input my number (both the 7 digits and even trying with leading zeros), my *A Gold status is not recognized...and I think it's got to be because of the number.
My US number is a 400xxx and is 11 digits in length, while my DL number is 22xxx and is only 10 digits in length
AA # is 6 digits joined in 1981 USAir is a combination of #'s and letters,7 total Unsure as to joining date.
