Yes, there are FTers, but I don't know if they'll come to this thread.

If you read all the threads in airline forums for people discussing and asking for help with booking saver tickets, there you'll find that some people are only looking for coach tickets TATL/TPAC. If all you look is threads about people churning cards to no end, maybe you don't see the same thing.

Keep in mind that not all FTers know how to get an "infinite" number of miles/points. For example, some want to travel with a family of 5, and just can get enough for coach for 5 TATL roundtrips, and then are still plagued with the trouble of getting 5 coach saver awards on the very same flights.

Also, it depends how people deal with sleep, and their size. Short people who sleep easily even if sitting upright may have a lot fewer issues with flying economy than taller people who have trouble sleeping upright.
