To be honest in my 'pre-FT' life I would have instinctively agreed with him. The entry level status I held just wasn't giving me much and I redeemed miles for Economy flights only. I had no idea about spacing out credit card signups and multi-carrier tickets on an alliance.
Of course the article is garbage and not based on facts but most peoples' gut will agree with him (not with FT)....This might be a good thing as it leaves more room for us here.
