Hi,
I used Hyperdia to search for Hakata - Beppu.
I deselected Airplane, Nozomi and private rail.
Search resulted with a basic fare and a seat fee.
Why is there a seat fee? Can I do away with it? See below.
Route2 Take time: 142 Minutes Transfer: 0 Times Distance: 188.0 km
Total:¥ 5,570(TicketFare:¥ 3,670 Seat Fee:¥ 1,900)
Hope you can clarify. Thanks.
