Narrative:

Crossed runway 24R with clearance, but was confused with another airplane. Landed on runway 24L, turning off at second high speed taxiway D4 to hold short of runway 24R. Before stopping at runway 24R, we received clearance to expedite across runway 24R and turn at delta 2. Our airplane was confused with airplane landing behind us exiting on delta 2. The controller confused the aircraft numbers and cleared us across runway 24R. Before crossing runway 24R, we looked for traffic. Runway was clear except for departing aircraft that was passing above us. There was no conflict.
