I usually receive ticket confirmation within minutes. That is odd that you are not getting confirmation within the day at least.
Kinda off topic - the below is like the opposite....
I actually wanted to comment on the fact that last week I purchased a ticket from a third party website. (usually when I do this the flights do not show up on my onepass accnt, so I cant manipulate seats and what not.) So I was pleasently surprised when I logged on to co.com that the information was there within 30 seconds of when I clicked on Purchase on the original website to logging on @ co.com!
