You'll have access to the Flash Pack app once your adventure becomes guaranteed (or as soon as you book if you book an already guaranteed departure). The app will contain useful information such as packing suggestions, visa and entry requirements, advice about travel insurance and more.
Your full, detailed itinerary will be available in the app as soon as your adventure is guaranteed. Please note that the itinerary is only finalised 30 days before your adventure begins. While it's rare, changes can still occur (around 5% of the time) and these may include hotel adjustments.
