Yes I too was a bit surprised not to see the GF product featured at all. However, the BF product is probably a bigger moneymaker for UAL, and since the ads are targeted at business travelers, focusing on the products which appeal most to that market segment (E+, power, wifi, flat beds, etc.) makes sense for this first run of ads.

I would imagine BF (two and three cabin) has a much higher % of paid traffic than GF.
