longhaul F has highest dollar value
domestic F may have some of best dollar to point value
i shouldve tried buying miles when i booked domestic transcon last minute
(2 middle seat Y / buying miles = $1500 per, i paid $2200 per for 2 F)

hotels can be crazy expensive, whether regular rate, or holiday rate (SPG)
but hotel point systems vary dramatically, and whether earning via CC or stay
credit card earning might be better for air, generally speaking
but if one never earns via hotel stays, just depends

blogs have to oversimplify and overgeneralize
some on FT do the same
it is really not ideal to try to do that
especially when perceived value varies
