On my recent four segment flt with KE, one thing that stood out to me was the size of its FAs. Yes, size. Slim. They all seemed to have come out of the same mold. I've even commented to my wife about it and she agreed, even though I didn't get any miles with her. On the last leg I was tempted to ask if KE pre-screens prospective FAs for specific measurements.
On another note, there were couple matrons that looked like they had some flights under their belt. They looked older than me, wrong side of average lifespan, and I don't wear make up.
