Why was it developed and built?

The Boeing 757 was developed to fill the gap between narrow-body and wide-body aircraft.

It was designed to be more cost-effective than the larger wide-body jets while having a higher range than the smaller narrow-bodies.

What purpose does it serve?

The Boeing 757 is used for passenger flights, cargo transport, air ambulance, and VIP services.

Its small size makes it suitable for short-to-medium haul flights, while its range makes it an ideal choice for transcontinental services.

How are the Boeing 787 Dreamliner and Boeing 757 different?

If you’re in the market for a new Boeing airplane, you might wonder what the difference is between the Boeing 757 and the Boeing 787 Dreamliner.

Both are popular models, but which is the better choice for you? Here’s a look at the primary differences between these two Boeing aircraft to help you decide.

Fuel Efficiency

One final difference between these two Boeing aircraft is their fuel efficiency. The Boeing 757 is not as fuel-efficient as the Boeing 787 Dreamliner. 

Finally, it depends on your needs. For larger aircraft, the Boeing 787 Dreamliner is your best bet. And for shorter flights, the Boeing 757 can be more cost-effective and fuel efficient. Eventually, the decision will come down to what you need and want from your aircraft.

How are the Boeing 787 Dreamliner and Boeing 757 similar?

The Boeing 787 Dreamliner is a cutting-edge airliner with incredible range, fuel efficiency, and cabin comfort. But what if you’re more familiar with the older Boeing 757? In that case, you might be wondering how the two planes compare. Let’s take a closer look:

Twin-engine planes

That means they have two engines mounted on each wing. The engine type is also similar; both planes use turbofan engines. Turbofan engines are powerful and efficient, making them ideal for long-haul flights.


Both planes can fly for over 5,000 miles without needing to refuel. That means they can easily cover long distances, such as transcontinental flights. That makes them perfect for medium-sized airlines.

What’s better about the Boeing 787 Dreamliner?

From its advanced fuel efficiency to its spacious and comfortable interior, the Boeing 787 Dreamliner has a lot to offer passengers and airlines alike. Here are a few reasons to like it.

Advanced Fuel Efficiency

One of the most crucial selling points of the Boeing 787 Dreamliner is its advanced fuel efficiency. It burns less fuel than similarly sized aircraft, thanks to its use of composites in its construction.

Not only is this better for the environment—it’s also great for airlines’ bottom lines. With fuel prices continually rising, anything that can help reduce an airline’s operating costs is a significant plus.

Comfortable Interior

The Boeing 787 Dreamliner was designed with passenger comfort in mind. The aircraft features more oversized windows, higher ceilings, and enhanced ventilation, all of which create a more pleasant flying experience. In addition, the Boeing 787 Dreamliner’s illuminate mood lighting can help reduce jet lag and make long flights feel shorter.

Quieter Ride

Another benefit of the Boeing 787 Dreamliner’s innovative design is that it results in a much quieter ride for passengers. The engines are located further away from the cabin, and sound-dampening materials are used throughout the aircraft. This makes for a peaceful flight and happy passengers!

What’s better about the Boeing 757?

The Boeing 757 Is the Best Plane for Short to Medium Haul Flights. Here’s what makes it better:

  1. Comfortability. The Boeing 757 is designed for passenger comfort with a spacious cabin and large windows. You’ll appreciate the extra legroom, especially on longer flights.
  2. It’s fast. With a cruising speed of 461 kn, the Boeing 757 will quickly get you to your destination. And with a range of up to 7,250 km, the Boeing 757 can get you there non-stop.
  3. Nothing beats its efficiency. With its twin engines, it uses less fuel than other planes. That means lower operating costs for airlines and lower fares for passengers.


The Boeing 787 Dreamliner and the Boeing 757 are both capable aircraft. The Boeing 787 Dreamliner offers advanced fuel efficiency, a comfortable cabin, and a quieter ride, while the Boeing 757 is ideal for short to medium-haul flights due to its speed and efficiency.

Finally, it depends on the airline’s needs. Both planes offer great value for airlines, and both can make air travel more enjoyable for passengers.
