The guy KABC in Los Angeles is interviewing ("John" Regional Safety Director, Airline Pilots Assn.) has flown the A319 and A320 and claims no fuel dump capability.
Max landing weight is 142,000 pounds v. max weight of 170,000 pounds. Relatively little disparity as far as commercial aircraft go, so not much need for fuel jettison capability -- except in situations like this.

I would guess that if the plane does NOT have fuel dump capability, they would keep it in the air for the next 3/4 hours to burn the fuel off.
so they're trying to fly fuel off?
