`find_trips`Find the cheapest return flights from a departure airport that fit a break, one per destination, cheapest first, with booking links.

`get_school_holidays`School holiday dates in the UK for a calendar year (half terms, Easter, summer, Christmas, and training days).

Every holiday says which it is. Academies and independent schools can set their own, so tell the person to check their school's.
