Thanks for that - total of taxes/fuel surcharges seem reasonable given the routing.
I was hoping that you would be able to tell me of a fantastic fare from Brazil to Amman but not to be. The best I have been able to find on Oneworld in Business Class is $2500 all in - not too bad when I can upgrade the GRU-DFW and ORD-LHR to First with an EVIP.
