The Seven Shades is an airship which travels from Tangier to London. It allows for 1 suitcase (but a nominal price can be paid up to carrying 3) and costs a whopping £12,000 owing to Fogg's newfound fame.
The route is unlocked after talking to a Jewish merchant and an Andalusian emigre in a shadowy bar in Tangier. Due to the morning departure of the Madre de Deus from Lisbon, it ends up being one day faster than that route (not accounting for any delays about the Madre de Deus's departure or in the car route to Lisbon).
