Are some or all of you finding that the Aeroplan-issued confirmation code only works online for certain airlines?

I was able to log onto US Airways to select my PHL-FRA flight, but the same Aeroplan confirmation code, and/or the US Airways code wouldn't work on SQ, TG, nor NH.

Should this be instantaneous (or take a business day or two) to generate another confirmation code? I do have two 014xxxxxxxxxxx numbers, but they don't work either.

In the past, as I've posted above, I just used AC's code to call it in to SQ, TK, CA, etc. but I'd rather do it online, rather than spending 10 minutes on hold * however many airlines I have to call.

**I was successful in accessing NH's online system after entering the second of the two 014xxxx numbers.*** Hooray!

One more edit - I had to enter the 2nd leg of my NH flight to gain entry into the booking management portal.
