1 kilo of wood sequesters (temporarily for the most part) about 2kg CO2 equivalent, so for the GP's example of a single seat one-way from Boston - NYC, you'd need to sequester 350kg of wood.

To sequester the ~800 Mt of CO2 emitted by aviation annually, you'd need to sequester about 400 billion kilograms of wood. So a finite but absurd amount.

Not only that, you have to build new wooden airports every single year to keep up.

Or you transition the airline industry to biofuels that are inherently carbon neutral.
