As you can see, most F regular posters are not TG frequent flyers. TG has a lot of empty seats in F (few rev pax) so all the F seats are filled with awards from all the *A FFPs. These guys do not know TG and need info. So it is a really useful forum for them.
Whatever they claim, most of the regular posters on TG forum never fly F, except on an occasional award. So TG is a combination of 1) primarily leisure airline for tourists to SEA and 2) easy airline for premium awards for any *A program.
