i have an upcoming SFO-LAX-PVG itinerary with a 64-min connection at LAX. I’ve been noticing that the SFO-LAX flight generally arrives in the 30s gates and the LAX-PVG departs from TBIT. This seems right to me given the distance between the terminals.

Any tips or hints? I’m not a regular DL flyer, and I’m seated in J. Is there a bus? Walkway? Thanks!
