Human: How can I find the best deal on an airplane ticket? Assistant: 
The best way to find a great deal on an airplane ticket is to shop around and compare prices between different airlines. You can also use online travel sites to search for flight discounts and promotions. Additionally, you should look for cheaper days to fly, such as midweek flights instead of weekend flights, and check multiple airports to see if there are cheaper tickets available. Finally, be sure to take advantage of discounts like frequent flyer miles, student discounts, and senior citizen discounts.
