What is a travel request form?
A travel request form asks for approval to spend on a business trip before anything is booked. This cheat sheet covers how to think about one and how to fill it out. The detail is further down.
How to think about it
- It comes before the trip. The request form holds estimated costs. The expense report comes after the trip and holds actual receipts.
- The estimate is the point. A cost estimate moves the budget conversation to before the booking, not after the expense report.
- Make exceptions explicit. If the trip needs an exception, like a hotel above the nightly cap or a non-preferred airline, the requester explains why in one line.
- Keep it to one page. Every extra field is a reason to skip the form and book anyway.
How to fill out a travel request form
- Enter traveler and trip detailsName, department, manager and cost center, then destination, dates and a specific one-line business purpose.
- Estimate the costEstimate each category before booking, such as airfare, lodging (nights times nightly price), ground transport, meals and registration fees.
- Check it against the policyIf anything falls outside the travel policy, mark the exception and explain why in one line.
- Route it before bookingSend it to your manager for sign-off as soon as the trip is confirmed.
- Keep it for reconciliationFile the approved form with the expense report so finance can compare the estimate to actual spend.
What published request forms include
Engine reviewed 25 published travel request and authorization forms from universities and public agencies.
| Field | Share of forms | Why it matters |
|---|---|---|
| Destination, dates and business purpose | 100% | The core of every request |
| Pre-trip cost estimate | 96% | Most broke it into line items rather than one total |
| Funding source | 96% | A cost center, project or job number, or grant code |
| Second approver beyond the manager | 92% | Usually finance, a budget owner or a dean |
| Policy-exception field | 16% | Rare, but it cuts the email back-and-forth after a request comes in |
How it works on Engine
On Engine, out-of-policy requests happen inside the booking flow instead of on a separate form. With Engine Approvals, the traveler gives a reason and submits the request, and the approver gets an email or text, reviews the current price, then approves and books or declines with a reason. Requests expire after 24 hours, or at the end of the reservation day for same-day stays.
Questions
Do I need approval before booking a business trip?
Most organizations require it. Of 25 published institutional travel policies Engine reviewed, 84% require pre-approval before travel, and 91% of a sample of private-company policies do.
How far in advance should I submit a travel request?
As soon as the trip is confirmed. Only 1 of 25 published policies Engine reviewed sets a minimum advance booking window.
What's the difference between a travel request form and an expense report?
A travel request form is filled out before the trip to get approval to spend. An expense report is filled out after the trip to get reimbursed. Keeping them together lets finance compare estimated and actual costs.
Who signs a travel request form?
Usually the traveler and their manager, with finance added for trips above a budget threshold. Among 25 published forms Engine reviewed, the most common structure was three signatures, traveler, manager and finance.
