Will I be able to book a commercial electrical flight between London and New York in 2040?

Prediction market on manifold. The price needs to be lower than a business-class flight today, £8k, inflation-adjusted. If the flight is driven by part fossil fuel and part electrical flight it does not count (except for reaching cruise altitude, see discussion in comments!).
