Thanks for the question.
After looking into it, I found out that 60.22% of FlyerTalk traffic is U.S. ISP-based. Even if you take into account the high likelihood of traveling Europeans in the U.S. visiting FT, and vice-versa, that 60% number, I think, likely balances out.
(In case you're curious, the second-largest representation is from the U.K., followed by Canada, then Australia. The rest after that are countries that have English as a second language).
Thus, by the sheer numbers, there's likely going to be at the very least a perception of U.S. bias.
What they say about perception being reality holds true. And I'm not going to say there is no bias -- there is one. We may slightly differ on the intensity of the bias, but if you have the feeling there is one, that is definitely something that will be on my mind as a TalkBoard member.
Thanks again for your question. And I hope to earn your vote.
