Hi There,
I want to check and see how much is the taxes, fuel surcharges you paid. I know routings can be different, but when you max out the 20 segments, generally you will pay around the same (assuming you will past through LHR at least twice)
Currently I am planning to issue a DONE4 with CX as the MPO can change the reservations efficiently. I want to compare the tax difference between CX and AA
