Does a channel lineup for the new Xfinity Sports and Entertainment Package in zip code 21218 exist anywhere?
It usually comes on the monthly statement about once each year. Called: Channel Lineup.
It gived effective date alone with 1-800-xfinity.
It would vary by service area. I would either visit my service area for one, or call the number to have one sent to you. I did not happen to find one with a link on my site.
