Since when? AFAIK only upgrades at the gate don't always get reissued. If it clears before the gate the ticket is supposed to get reissued. If you have IRROPS and ticket hasn't been reissued then they don't have to keep you in D1/Business. The ticket is the important part to ensuring you get into J.
