Foreign Exchange - Guest want to change a reservation done in advance

[Georges10]

If the guest make their reservation in advance and later need to change to include another guest or more days, this will impact the amount being paid for the part already settled, since you have to cancel and start again. May be I am wrong, but due to exchange rate changes this situation could impact the host or the guest depending on the currency fluctuation. Here an example, if someone books in January for a 15 days period in June, the reservation will be closed with January exchange rate. If later in May guests want to change the reservation to include one extra day and one extra guest we will have to cancel the reservation and do it again, a new exchange rate will be used to the whole period. This will impact one part (host or guest) depending on which currency devaluate against the other. In Latin America we have a lot of exchange rate fluctuation during the year due to several factors it can increase or decrease against other currencies.  Is there a way to avoid this issue? Allowing to have just the change in the reservation be charged in new currency?

You don't ever cancel. The 'Change" function shown with your reservation is for making changes in dates, no. of guests, prices.

Ummmmm.....Don't CANCEL!!!!!  That counts against you and you will never make Superhost.  It also puts you lower in the search list.  Go into the reservatation and click on the "change reservation" link.  Then go in and make the changes.  If you can't figure it out, call Airbnb support and they will assist you.
