Ever since an "upgrade" to the international OLCI system sometime last October or so, I'm not able to use OLCI for international tickets on Delta.com. AF and KLM have no problem handling the same reservations.

At first, the system would claim my passport number was invalid--needless to say, it is not. It is a bit wierd, has five 9s in it, but certainly it is valid. Calling in and talking to web support yielded a suggestion to preceed my passport number with "US" or "USA" with and without spaces between the prefix and the number. None of those worked though.

Recently, there was another "upgrade" to the system. I no longer get told that my passport number is invalid, but it just konks out at the point I'm asked to insert my passport information and tells me there's an error of unspecified type.

I've tried escalating it internally twice (both over the phone and through the internet) and gotten no response and no remedy in over 5 months.
