Best seats for BKK to FRA

On long-haul flights of this length, sit forward of the wing for the smoothest ride. Seats in rows 10–20 of a typical wide-body are over the wing's center of lift and feel the least motion.

Over the wing — the aircraft's center of lift moves the least.
Forward of the wing — second-best, slightly smoother than the rear.
Aisle seats — psychologically calmer if you don't enjoy looking out.

Is the Bangkok to Frankfurt flight safe?

Yes. Commercial aviation on this corridor runs at roughly 0.02 fatal accidents per million flights — about 1 in 50 million. Modern aircraft are stress-tested to handle far more turbulence than they will ever encounter. Wings are tested to flex up to 2× their normal range without breaking, and the structural margin is many multiples beyond what a typical bumpy flight delivers.
