I would like to know the shortest route from Illinois to Portland in Oregon in the shortest possible time. I stay in Springfield. So I would like to have details about airports, where to board and where to get off so that travel time is minimized. And also I do not wish to change flights and would like to travel directly.

You can log on to http://optifly.com for convenient air travel in all respects. The site is very user-friendly and you can enter your starting and end destinations for available flights and their costs. By doing this, you will also come to know whether there are any direct flights or hopping ones and can choose among them .
