The Bookings Analysis report template is only available to Teams on certain pricing plans. If you can't see it, it is not relevant to your team.
The default Bookings Analysis and Travel Analysis report templates both have the same columns and pivot tables. The difference is in their contents.
The Bookings Analysis report template includes special services which are booked by our agents on your Team's behalf: Additional Services and Events.
If your team doesn't make use of these 'offline' services then you can simply run the Travel Analysis report.
If you're not sure, you can run the Bookings Analysis report as it contains everything that's in the Travel Analysis report.
