Ok - This started yesterday and I'm wondering if it's just me.

Every time (well, most times) that I try to reserve a domestic flight on co.com, After the page where I agree to the terms, I am taken to a page which says that I cannot book the fare due to an incorrect country of residence. I am in the US, I'm on the US site, my OP # is in & I'm signed in. I called co.com support, they walked me back through the reservation, and that time it worked (figures). It seems that when I get the error, I don't get the drop down box from which to choose travelers. When I back up and try again, 50/50 I get past the error to seat assignments. When I accept and continue (whether or not I use the seat map) I then get a non-descriptive error message about 75% of the time.

Before I call co.com back and walk through this, I was basically wondering if it's just me... perhaps I have a local issue with my browser, cookies, cache, whatever (although I repeated with with ie, mozilla and firefox (firefox on WXP and Linux).

I have no immediate issue as eventually I was able to get everything entered... just a real pain to get that far.

And just an FYI - co.com did say that this happens sometimes when entering youthful passengers or children when the flight is domestic - seems that their IT wizards decided that since there are no fare differences or tariff requirements to differentiate children on domestic flights, if you enter them they assume it's an international flight and confuse the system. I subsequently repeated the problem without entering children, and on a reservation for myself, alone.
