There have been many threads about missing brel re-entry tickets.
In all of these, it appears no one has received a Gate 2 re-entry ticket. Many people believe that Gate 2 is bugged and does not grant re-entry tickets if players are disconnected from it.
This may have been confirmed by Customer Support in the following live chat reply:
