Thanks for the article. I too got the email from Expedia.
It's probably a form reply, but here it is:
<font face="Verdana, Arial, Helvetica, sans-serif" size="2"> Dear Expedia.com Customer,
Thank you for contacting Expedia.com regarding ticket sales on Northwest Airlines.
Expedia.com has discontinued ticket sales on Northwest Airlines. Be assured
that we are still supporting all Northwest Airlines tickets that you may have
previously purchased on our site and that the tickets will still be honored by
Northwest. We are engaged in discussions with Northwest and hope to reach an
agreement. Our customers will continue to be able to obtain tickets on the
other major carriers - as well as access Expedia's world-leading array of
hotels, packages and cruises.
If you have any further questions, please feel free to reply to this e-mail.
Thanks for choosing Expedia.com!</font>
Even if NW was paying Expedia too much, I don't think NW can afford not having it's flights and fares displayed on one of the top US travel websites.
