Well I use TG/NH every year multiple times from the east coast or japan to BKK - I'm quite happy with the service and mileage expense (for F) - but then again bc of where I fly from it's easier for me.... I also spend at least a week in Europe every summer for holiday - never had a problem finding F space to most places (if done far enough in advance and with flexibility) - LH F is one of my favorite pleasures....
