Army-Navy tickets for the Class of 2011 go on sale June 13 and close June 30. I have always advised parents to go over to the NAAA ticket office on I-Day and sign up for tickets. The extended continuing dominance of Navy over Army has caused the Navy allocation of these tickets to become a premium. Since 2011 is the last block to open and close, there is a chance that all tickets will be sold out before the end of this window. My advice is this year to call the ticket office 1-800-US4-NAVY on June 13 and get at the top of the list. You may be able to do it online. Not sure. I think each candidate rates 2 tickets. You will probably need your candidate's Alpha number to process the order. I am certain that Army parents will not have this problem.
