Around 15-20% of the cost of the lifetime of a jet aircraft is fuel. Electricity is much cheaper than fuel, so that would mean significantly lower ticket prices. Of course, such aircraft can only fly on routes shorter than their maximum range, so they will only compete with jets/turboprops on regional flights.

Even if the initial cost of an electric plane is higher than a combustion equivalent, the cost of the aircraft itself is only 5% of its lifetime cost. So an electric aircraft's purchase price could be twice as much and still represent a cost savings for an airline. And that's not even counting other advantages such as reduced maintenance needs for EVs.
