For example if scientists develop an aircraft which can take off from point A and enter into space and then travel to point B it would arrive to point B much more quickly than if it were to take this flight within earth's atmosphere because the speed in space is about 17000 mph?

What you just described is an ICBM (intercontinental ballistic missile) which have been around since the 1970s for use as delivery systems for nuclear warheads.
There is no set "speed in space". 17000 mph is just some arbitrary value that you chose which would only result in an orbit at one specific altitude.
Space travel is still way too expensive to employ for commercial air travel between two locations on the same planet. The amount of energy expended by conventional rockets would be a complete waste if you were just planning on re-entering Earth almost immediately. If you thought backage fees were expensive before, expect them to increase by about 100 times.
Planes cannot fly in space. Jet engines require air to function (the large fans on the front of the engine pulls air into the engine's compressor). No matter how advanced an aircraft gets, the only way to fly in space is some sort of rocket.
The more plausible way to make air travel faster would be to use supersonic aircraft for commercial use. The Concord demonstrated this concept. Supersonic aircraft are shaped much differently than subsonic aircraft because the fluid dynamics change completely upon entering the subsonic regime. You could reasonable achieve mach numbers of 2-3 (usual commercial aircraft fly at mach numbers of about 0.8), which would cut your flight times significantly.

That is scientifically possible but (so far) not economically possible. In fact air travel today is a bit slower than 30 years ago. Back then the average speed of airliners was a bit higher, and the supersonic Concorde was flying. Now the Concorde has been retired due to the high cost of flying it, and technology of new airliners has concentrated on efficiency, fuel economy, and safety, while giving up a few miler per hour of cruising speed.
