Yes, a white label travel portal normally gives you booking reports you can read yourself without asking anyone for help. In most setups you can pull your bookings for a chosen period and group them by product type, by destination or city, by the supplier the booking came from, by the staff member or sub agent who made it, and by status such as confirmed, cancelled or pending. That is usually enough to tell you which routes and which cities your customers actually buy, and which suppliers you are leaning on most.
How deep the reporting goes does depend on your plan and on what each supplier sends back to us. Some suppliers return rich detail with every booking, and some return only the basics, so a field you want to group by may be blank for part of your sales. It is also worth being clear that a booking report tells you what people bought, not what they looked at and walked away from. Search volumes, popular pages and where your visitors came from sit in the website analytics tool connected to your portal, so you would normally read the two side by side when you are planning where to spend on marketing.
Most portals also let you export a report to a spreadsheet so your accounts person or your marketing agency can work on it, and some plans allow a report to be emailed to you on a schedule rather than you logging in to run it.
The practical next step is to tell us the handful of questions you want answered each month, then check in your portal which of those your current reporting covers and which would need an export or an extra analytics setup.
