Right, but if you buy a package, you still have ZERO risk of ending up with very expensive, non-refundable tickets. You WILL run that risk once you link your tickets. They are non-refundable at that point. If something happens within 60 days of your trip, you're out of luck. Someone who booked a package and cancels within 60 days, does not run that risk. They will risk cancellation and change fees if something happens within 30 days, but they can always avoid that by simply re-scheduling their trip.
