A simple structure to coordinate transfers, changes and confirmations.
Start with the complete itinerary
Share origin, destination, schedule, passengers, luggage and all planned stops. The operational context is more useful than a vehicle name alone.
Confirm responsibilities and communication
Use one updated itinerary and define who can approve changes. This reduces conflicting instructions.
Leave realistic operating margins
Include terminal exit, access control, traffic, loading, unloading and possible schedule changes. A better buffer protects the agenda.
Conclusion
A more accurate quote starts with complete information. Share the itinerary and let the vehicle be recommended according to the real operation.
