Tengo reservas de Maersk Spot hacia/desde los Estados Unidos de América. ¿Tengo que cancelar y volver a reservar cada vez que hago un cambio en estas reservas? Is Maersk Trade and Tariff Studio a one-time analysis or an ongoing service? Can I amend a booking after it has been confirmed? Will I be able negotiate or buy more free time days?  Will I be able to see my deadlines? Can I still book if I am not sure about the cargo details? How quickly will I know if my booking is accepted? Why can I no longer access Lock Rates on Maersk Go? Will I still have the same access to booking as before on Maersk Go? Do I need to input the accurate cargo weight and volume at the booking stage? Can I add Freetime Extension to an existing booking? Can I add or delete containers in my booking?
