Due to weather enroute and airport congestion; we were less than 15 minutes from CCO (Critical Crew Off time) on originating flight. Late to ZZZ1; fatiguing without [Relief Pilot]. On departure; fuel critical. Waited 45 minutes for final weights. Only resolved after 2 calls to Dispatch. Even with one engine shutdown (one stayed running for taxi) we were in jeopardy of returning to the gate for fuel or missing CCO. Now already over 8:00 block with no [Relief Pilot].  Slightly higher fuel burn than on [Forecast]. Re-routed for thunderstorms over ZZZ.  Routed down [the] coast then back west.  ATC was great getting planes around the storms to west of ZZZ.  Other flights diverting; our bingo was 10.0 with ZZZ2 [as] our divert.  ZZZ now VFR; we had field in sight; fuel now less than 10.0.  Slam dunk into XXR; runway changed due to other lower fuel aircraft getting priority.  Did not realize we did not do the Landing Checklist until touchdown. Obviously gear and flaps were in the proper position.
B757 Captain reported that due to several route changes in flight; flight crew failed to perform the Landing Checklist.
