How do plane turns while at their cruise altitude?

It is quite weird how planes turns while at their cruise altitude? Does someone know how they do this?

Bank to the left or right? Like normal? What’s confusing you

They probably bank really gently so you barely notice it.

Not only so that passneeges don’t notice it, but gentler banks means they dont loose as much airspeed in the turn.

Ahhh I see. You see, when planes are cruising, they try not to turn at all at say 36000 feet, for passenger comfort, meal service etc. If the plane was turning at cruising altitude, meal service wouldn’t be served. When a plane does turn, the pilots use their heading.

As opposed to using their speed to turn?

i don’t think the bank angle is greater or less then when at lower altitudes, however die to the higher speed the corresponding centrifugal force is greater so is not noticed so greatly

I never noticed it while in flight.

They often use inboard high speed ailerons and inboard spoilers, whilst the outboard ailerons are locked out.

These are naturally quite small to avoid too much twisting on the wing. High speed aerodynamics mean you do not want to plane to be too active or “twitchy”.

The term “jet upset” comes to mind.

I don’t understand what you mean by this.
