If your trip isn’t open for booking and shows as Sold Out or Waitlist, there are a couple of things you should check:
Go to Trip Manager > Basics
Make sure your trip dates are not in the past.
Check the "Last Day to Book" field—it should also be a future date.
Then go to Trip Manager > Packages
Look at the Package Dates and confirm they’re still active (not expired or set in the past).
If any of these dates are incorrect or in the past, update them—and the trip should open for booking again as expected.
