I flew from Ireland to France recently and then caught two trains to my ultimate destination about 100 km from the airport.
The train fares worked out at double the cost of the flight despite being one fifteenth the distance.
I still can't get my head around the fact that we as a society allow air travel to dump that much environmental costs on all of us. If flying had to internalize the cost for externalities into the pricing your plane ticket would have probably cost way more than the price of the train ride.
