My complaint:
I tried to redeem Avios to book a flight in Japan (original price JPY 11710). Japan airlines only requires 6000 miles plus JPY 710. But Qatar Airways asked me to pay JPY 11,090 as pet tax of the flight which is even more than the flight fare itself. I contacted JAL, they said they do not impose any extra tax! So it seems Qatar Airways is scamming its customers as well as partner airlines!
Suggested solution:
They need to investigate Qatar Airways operations on mileage redemption. It is a scam.
