No, traveling from east to west in an airplane, regardless of its speed, does not constitute time travel in the sense commonly understood. While it is true that you may experience a change in time zones as you travel across different longitudes, this is merely a result of the Earth's rotation and the division of time into different zones for practical purposes.
The concept of time travel, as often depicted in science fiction, involves moving backward or forward through time itself, not just experiencing changes in local time due to geographical movement. It implies the ability to manipulate the flow of time and visit different points in the past or future.
The effects of high speeds or relativistic travel, as described by Einstein's theory of relativity, can introduce some peculiarities, such as time dilation. This means that time can pass differently for an object moving at a high velocity relative to another object at rest. However, this effect is negligible for speeds typically achieved by airplanes and only becomes significant at velocities close to the speed of light.
So, while air travel can result in changes in local time due to time zones, it does not grant the ability to travel through time as commonly imagined in science fiction.
