That flight is about 230 miles (365 km) as the crow flies, and they're doing it with 737s that seat 100+ each and fly dozens of these flights a day.

Compare that to this battery plane that can fly 200 miles: https://cleantechnica.com/2020/01/29/rolls-royce-claims-its-...

These aren't in the same ballpark; they aren't even playing the same game. If you want something to replace that plane route, I suggest buying a lot of buses.
