☀️ Morning Flight

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

Weather conditions can change. Check again before your flight.
Regional Jet (Small)

Regional jets are smaller and lighter, so turbulence may be more noticeable to passengers. However, they are fully certified and safe for all weather conditions.
