According to the CO website (
http://www.continental.com/web/en-Us...lliance.aspx):
"Continental will end its participation in SkyTeam after our last scheduled flight on Oct. 24, 2009."
Therefore, I can't foresee any problem with accessing SkyTeam benefits, such as lounge access, up until the end of that day. You should be just fine tomorrow.
Beyond then...I have no idea.
