Airlines Exchange Rates
I know that airlines use a lot of different terms in regards to currency exchanges. i.e. IATA (CDR) (FDR) (MMR) and I have heard many RTW ticket agents refer to the BSR. Does anyone know on what date QR, CX, and AA update their BSR and how long is valid ? I know in the past it could make several hundred dollars difference in the price of a DONEX versus the actually exchange rate on the day the ticket is quoted.
Thanks
