Estimate event travel costs per attendee with AI and submit fund requests in minutes
A B2B software company replaced manual travel research with AI agent fields in Airtable that auto-estimate airfare and hotel costs for each attendee, roll up to a total, and flag over and under estimates before funds are requested.
The problem
Event planners spent hours manually researching airfare and hotel costs for each attendee when preparing cost estimates for in-person events. The process was time-consuming, prone to inaccuracies, and provided no real-time visibility into how estimates compared to actuals as attendees were added or removed.
Submitting fund requests required a separate, manual step that was disconnected from the cost model. There was no formula-driven view of total estimated costs, no tracking of which estimates were over or under target, and no integrated path from the cost model to the fund approval process.
What they built
The team built an event planning base in Airtable that lists attendees and locations as records. AI agent fields run automatically for each attendee record, pulling live data from AI web search to estimate airfare and hotel costs based on the attendee's origin and the event location. A per-diem field rounds out the per-attendee cost model without manual input.
Formula fields roll all per-attendee estimates up to a total for each event, and an over/under tracking column shows how the estimate compares to target in real time as attendees are added. When the cost model is complete, event planners submit fund requests directly through a Ramp integration, eliminating the offline step and keeping the approval process connected to the data that produced the estimate.
The outcome
Event cost models that previously required hours of manual research are now completed in minutes. Planners enter attendees and a location, and the AI fields generate per-attendee estimates automatically. No manual travel lookups are needed, and every estimate is produced from the same live data source rather than from individual research sessions that can vary in quality.
The over/under tracking field gives event planners and finance teams a real-time view of estimate accuracy as planning evolves, and the direct Ramp integration means fund requests are submitted from the same record that contains the full cost model. Approval reviewers can see the attendee list, the per-attendee estimates, and the total in one place before approving.

Event Planning & Budget Management
Add each attendee and their origin city, and AI fields estimate airfare, hotel, and per diem for that person, then roll every line up to an event total tracked against your target in real time. Automations log each estimate run, draft the fund request the moment a cost model is ready, advance the event when finance approves, and email a Monday digest of estimates flagged for review.

Add attendees and locations to generate per-person cost estimates with AI
Roll up estimates to event totals and track over and under in real time
Submit fund requests through the Ramp integration from the same record
FAQ
Frequently asked questions
AI agent fields in Airtable can be configured to query external data sources, including AI-powered web search, at the time a record is created or updated. For each attendee record, the field sends the origin location and event destination to the AI search and extracts an estimated airfare and hotel cost. The result is written back into the record automatically. You configure the field once and it runs for every attendee without manual input.
The estimates reflect current market pricing at the time they are generated, drawing from live search data rather than static reference tables. They provide a reliable starting point for cost modeling and fund requests. Planners can review individual estimates and adjust any outliers before finalizing the cost model, and the over/under tracking field makes it easy to see where the estimate may need attention.
A formula field compares the rolled-up total estimate to a target figure you enter for the event. The result shows whether the current estimates are above or below the target, and it updates automatically as attendees are added, removed, or their origin locations change. This gives planners a real-time accuracy indicator without needing to run a separate comparison calculation.
When the cost model is complete, an Airtable automation or button triggers the fund request submission to Ramp using the event total and attendee data already in the record. The request is linked to the Airtable record, so approvers can access the full breakdown if needed. This keeps the entire process, from estimate to approval, in one connected flow rather than requiring a manual handoff between tools.
Yes. Because estimates are generated at the individual attendee record level, the cost model naturally adapts as the attendee list changes. Adding an attendee from a new origin generates a new estimate for that person, and the rollup field recalculates the total automatically. Events with attendees from many different locations are handled the same way as those with a small, uniform attendee group.
