Yes. Airlines sometimes change their flight planned routes to take advantage of the jet stream when flying East, and avoid the jet stream when flying West.
In most cases that is planned to find optimum 'jetstreams' headed in the right direction.
Jetstreams are fast-flowing narrow air currents found in the atmosphere. They move from west to east due to the Earth's rotation and temperature differences between air masses. Jetstreams can greatly impact weather patterns and the movement of aircraft.
They vary every month. It also depends where you are flying eastbound to. If you are flying eastbound to the US from Asia across the Pacific to the USA, the movies are different than if you are flying eastbound on a transcontinental or indeed eastbound on a transatlantic to Europe.

It is a huge aid in finding reasons for accidents.
There is a polar and subtropical jet in each hemisphere.

Jetstreams can influence the movement and behavior of air masses by steering them along their path. The strong winds of jetstreams can cause air masses to be pushed or pulled in certain directions, affecting their speed and intensity. Jetstreams can also help to mix and create boundaries between different air masses, which can lead to the development of weather systems like storms or high-pressure systems.

By having airplanes, we win wars easier and faster and we can get aid to those in need, whether it be food or medical supplies.
In the foreseeable future humans will not fly without technological aid. Humans can fly today with technology such as airplanes.
