Once a traveler books a flight or a hotel and it sits in the cart for a certain amount of time - eventually that flight will become unavailable and the traveler will not know it's unavailable until they go and try to book it. No proactive messaging. Same thing on approvals side - once it goes to approval and it sits for a decent amount of time - it becomes unavailable but approver doesn't know.
Questions from client:
Do you know why this itinerary is no longer available when I try to approving this request?
Why can't the itinerary simply reprice vs disappearing entirely?
