1. Click into the trip you want to duplicate
2. Click on ellipses next to the 'share itinerary' button within the trip
3. Click on Duplicate Trip
4. Check or uncheck the data you want to bring into the new trip: Copy Prices, Commissions, and Payment Groups
5. Click on Duplicate Trip
6. Rename the copied trip to reflect whatever you're planning next
