☀️ Morning Flight

Morning flights typically experience smoother conditions as the atmosphere is more stable and thermal turbulence hasn't yet developed.

Narrow-Body Aircraft (Medium)

Single-aisle mainline jets like this offer a comfortable ride. While you may feel turbulence more than on wide-body aircraft, they are engineered to handle it smoothly.
