$77 per flight.

The European airline group Deutsche Lufthansa AG said it will start to add a surcharge of as much as $77 per flight next year to cover the cost of reducing emissions from jet fuel, Bloomberg reports.

The exact surcharge will depend on the specific route and fare. The announcement is an indication of the reality that reducing emissions associated with jet fuel is a very hard task.
