For my latest several cycle trips I have travelled with Qatar Air. They have a 30 kg baggage allowance and used to allow another 10 kg for 'sporting equipment', that includes a bicycle.
Yesterday when I went to buy another ticket with them they tell me that they no longer give any 10 kg allowance for 'sporting equipment'. Too bad!
I have been advocating for Qatar Air among all cyclists I have met and in my journals. I feel I have to tell you that I will no longer do that.
PS Turkish Air gives me a 46 kg baggage allowance. That is flying from Europe to Nepal. Don't know about elsewhere.
