Nearby country boards
Paris, Nice, Lyon, and ski-season add-ons work best when airport-to-centre timing stays visible.
Barcelona, Madrid, Malaga, and the islands suit short UK breaks when transfer time and baggage rules are compared early.
Rome, Milan, Venice, and Naples work well as open-jaw trips when the first hotel night is planned around arrival.
Lisbon, Porto, and Algarve breaks need hotel-area and airport-transfer checks before the cheapest fare wins.
