Stephanie does not book the lowest airfare available.
Her choice affects her company’s negotiated air contracts and savings opportunities.
Stephanie receives an email asking her to rebook a more economical flight:
Your flight reservation exceeds the lowest available price. Please change your booking to a less expensive one if possible. Choosing the lowest fare helps us stretch our travel budget.
Pre-ticket data triggered the email, so Stephanie is able to change her flight. Over time, her company improves travel policy compliance and controls costs through increased lowest fare acceptance.
