Hi,

Does it make sense to have following assumption: can not change the itenerary after it is paid.

Lots of thanks for your opinion.

Look for other tpics in this forum regarding this. I think this is the right approach. Most Airlaines does not offer a refund after the reservation have been paid. That's why you can buy a "cancel" insurances if you book a journey.

Don't forget to include this assumption in your documentation.

regards

Yes I would agree with your assumption because the Change Itinerary use case does not explicitly mention anything about this precondition.

In real world scenario the customer gets an option to buy non refundable v/s refundable tickets. The one with refundable option comes at a higher price.

But once you make this assumption, what is the benefit of Change Itinerary use case.

Simple one would be: User from payment screen opts to modify the itinerary.

Complex one would be: The prepare itinerary use case will allow the customer to prepare and optionally save unpaid itinerary, which can then at some other time be modified using Change Itinerary.

I am not sure if I am able to put my point across to both of you
