Aircraft; Procedure; Weather
I inherited the flight with approximately 2 hours flight time remaining. The dispatcher I relieved advised that the flight was overburning fuel by approximately 3000-4000 lbs. At the time of re-dispatch; they were legal to continue with original alternate of ZZZZ1; but they had very little extra fuel to work with. About 45 minutes prior to landing; the flight was advised by ATC of potential holding for ZZZZ; and the crew discussed diverting. I advised to go ahead and divert to ZZZZ2 at the point they were told to hold; due to their present location NE of the field and that ZZZZ2 has customs and favorable ground handling. The flight then elected to divert to ZZZZ2. While I was in the middle of notifying managers of the situation and preparing a diversion flight plan; the crew discovered they did not have sufficient fuel to reach ZZZZ2 and instead declared ZZZZ as their destination and declared a PAN PAN PAN with ATC. The flight was cleared in and landed with about 8600 lbs of fuel (approximately 50 minutes).
Air carrier Dispatcher reported an aircraft was over burning fuel and required priority handling on arrival.
