So we just flew in to Singapore from Zurich.

It was a good flight, only 25 passengers across the whole aircraft. Food service was great with plenty of snack runs through the night, including ice cream and sandwiches.

Anyway, what I wanted to ask was this..

Why do the middle row of Y seats have foot rest and leg rests while the window rows do not? Like I said, it wasn't an issue as the flight was empty and we could move where we wanted, I'm just interested to know why.. HB-JMA, if it helps

Thanks
