If you're worried about future generations you'd want to limit the effects of climate change, which means reducing carbon output. Sending more carbon into the atmosphere now means our descendants will experience more dramatic climate change impacts, and also need to reduce their output even more. Or to put it another way, the more flights avoided now the more flights can potentially be taken in the future.
