Emirates Complaints
I agree with FT101 and have travelled on QR abit. I think it will be a far worse experience the complaints process and new airport while it goes through not inconsiderable teething issues. On board is good but a different experience to EK so depends what you prefer.
As an aside if I were plat with a compliant I probably would follow up with a call to the plat line am sure they would then follow up more effectively.
