Everything else could be arguably compared to the time needed for a domestic flight.
You’re missing my point: I fly a 737 regularly to Hawaii and have to plot the chart and run through the ETOPS checklist, I’m just trying to wrap my head around why the same flight (or a transcon) would require more preflight preperation time in a 777 as Capt. Fitzgerald suggested.
