I have no status with CO anymore, but I still have DL silver. Earlier this year I booked a ticket on CO using my OnePass number. Only seats in the back of the plane were available and I chose one. Then I decided to change my Frequent Flyer # on continental.com to my DL Skymiles #. After I did that, the front of the plane became available and the website recognized my elite status.
