Chris, Jenny and Graham need to travel between Scotland and London, but at different times. Chris and Jenny both want to travel to Scotland on the 11 August, but while Chris wants to go back to London on the 15th, Jenny won't be going back until the 20th, accompanied by Graham, who will be travelling down to London for a fortnight's work experience. He needs to travel back up to Scotland on 4 September.

Jenny wants to sit with either Chris or Graham on each leg of her journey. The tickets should be able to be bought over the internet, where no special instructions can be made.

How can this be achieved?
