Task: Question Answering
Input (English): How do I compare cheap airline tickets on multiple websites?
Output (English): Aggregator websites are a good tool to use, due to their ability to show multiple website comparisons on one webpage, instead of multiple webpages. Type in your destination and travel dates on the webpage in the necessary locations, and click the button to make the aggregator site search for you. When it is finished, you can compare the results and select your preferred choice to book it.
