Good Morning,

I wanna know if it is commun , when you change your travel date, and in this date you're placed you are put in a class cheapest then the last one.( both are economy class)

If the company give the credit ( diference of the price between the classes) to the client ?

Or the company can not give the credit , and do a REFARE ?

Sorry if i am saying silly things, but i am confusing with the meaning of REFARE.

Thanks
