This is intriguing
Interest in ex-CAI RTW fares was rekindled in early Feb - [MENTION=873896]PO48RA[/MENTION] posted that the base fare for a DONE4 was USD4664 (see Post #1113)
Other posts at that time indicated that the base fares were in EGP (e.g. post #1119 told us the DONE5 base fares was EGP145,000)
But then early this month the fares were being quoted in USD, and were higher (DONE4 for USD5220 for example; I actually made a note of these fares on March 8th, but didn't note which OW airline's fares I was looking at)
And now the fares have reverted to being quote in EGP and are the same as they were before the change to USD

Note: I used experflyer to look up the current fares. It displays the fares in the currency you choose, but if you click on the routing rules (!) for a fare, you can see what currency has been filed for the fare

BUT the bottom line is - these fares are a bargain!
