What is interesting with Ben/OMAAT is that he has almost a Robert Parker thing going on when it comes to premium cabin reviews. Parker has reviewed so many high-end wines, and wine is a much bigger and moneyed market now than when Parker started, that to try all of the wines Parker has tried to reach his experience level and review with that experience will cost someone A LOT of money. Likewise, even with relatively fewer and fewer of them to go, it would cost a significant amount of money to fly all of the premium cabin products Ben has flown, especially as some of the better ones (looking at you LH 747-400 F...) are no longer around at all. There's a really high bar to entry to become what Ben is. And, while the blog model of credit card conversions will continue to decline, if Ben can keep up other revenue streams high enough, he can keep up being a premium cabin travel review blog for quite a while.
