Most people don't like the time wake-up times required to hit the earliest flights out of the airport, so a “first flight of the day” oftentimes offers less packed airplanes as well as easy breezy airport concourses. As a bonus, the early morning flights almost always have the best on-time records.

Statistically, early morning flights (departures before 7:00 AM) are often less crowded than midday or evening flights, though they are rarely "empty" in the high-demand environment of 2026. Many travelers, especially families with young children and casual vacationers, avoid the "3:00 AM wake-up call," leading to lower load factors on the first "bank" of departures. For business travelers, however, these are peak times, so "commuter" routes between hubs may still be quite full. The primary benefit of an early morning flight isn't just the potential for an empty middle seat; it is reliability. Because the aircraft is usually already at the gate from the night before and the crew is fresh, these flights are the least likely to suffer from the "snowball effect" of cascading delays that plague afternoon travel. Additionally, security lines and airport terminals are generally at their quietest during these pre-dawn hours, making the overall experience much less stressful, even if you have to trade a few hours of sleep for a smoother journey.
