  • Environmental concerns and rising fuel prices continue to affect the aviation industry.

  • Airlines are investing in new technologies to fight the challenges.

  • Future aircraft include supersonic jets and hydrogen-powered planes.

The need for more fuel- efficient and cost-saving aircraft is becoming a bigger priority for airlines as the demand for travel continues to increase.

The industry's CO2 problem is being solved by zero-emission electric take-off and landing aircraft.

Airlines like United and American are betting on electric air taxis that could change the way we travel.

A new way of travel between airports and congested city centers is being shaped by e VTOLs.

supersonic and hydrogen-powered jets are likely to hit the market in the next couple of decades. The aircraft of the future are on display.

The electric air taxi route between Newark Liberty International Airport and Downtown Manhattan is the first of its kind in the United States.

Electric flying taxis will change the experience of flying with airlines according to Delta.

The aircraft, which has a 150-mile range, has flown 1,000 test flights over the course of 10 years, and is expected to enter service as early as 2024.

The first test flight of an electric plane, called Alice, was completed by Washington-based Eviation.

A new electric plane just took its first test flight.

According to the company, the "proof of concept" aircraft will be zero emission and fly up to 288 miles. The plane is being ordered by a cargo carrier.

One startup is trying to fly faster than sound using 100% SAF, which is electric, V-shaped, and hydrogen-powered aircraft.

There are 7 passenger-jet concepts that will connect cities in as little as one hour and fly up to 9 times faster than sound.

Overture is an ultra-fast plane that will connect New York and London in 3.5 hours.

The new design of the ultra-fast airliner will allow it to fly from New York to London in 3.5 hours.

According to the company, the jet could operate with net-zero carbon. The jet has been invested in by several airlines.
