The Phenom 300 seats between 6 and 8 passengers, whereas the Learjet 75 has a standard 8 seat layout. It's worth pointing out that all 8 seats on the Learjet are individual club seats. Both aircraft have a separate washroom with a sink and the same cabin headroom. However, Bombardier does claim that the soundproofed door between the Learjet 75's cockpit and cabin combined with their flat floor design results in a more refined experience. As with many newer jets, cabin pressure on both private jets can be set at around 6500 feet, so passengers can benefit from arriving less tired and de-hydrated. Both private jets are also designed with internet connectivity in mind.
Both of these private jets are great choices if you're looking for a smaller but high performing aircraft that will get you comfortably to destinations around the United States. Whilst the Learjet 75 perhaps triumphs in terms of the on-board experience with its flat floor and club seat layout, the Phenom 300's high performance on short runways and its generous luggage capacity make it an equally good choice.
