The debate got more interesting. I can get on TG in F NRT-BKK-FRA but there's only a 1 hr connect in BKK. I could do TG in C to BKK and connect to F with time for a massage.
In general I prefer TG to NH in F (though my sample size for NH is 1), but taking NH allows me to get out in FRA and spend a few nightime hours in Wiesbaden or Mainz, neither of which I've seen before.
Plus, NH has all the Star Wars movies playing so I can finish watching the lot before The Force Awakens opens in December
TG: slightly better food, slightly better seat
NH: star wars movies, chance to take a peek at a new city
Choices, choices!
