MBAGrad, Can you help me again? Follow the steps below: Choose a Web site like Travelocity.com, or Expedia.com to book hotels, rental cars, and airlines tickets as part of a travel plan. Choose a city or a town you want to visit. This place can be situated anywhere in the world. Select three different time periods in the year: winter, summer, and fall or spring. For each time period, book the following: An airline ticket from the nearest city with an airport to your destination A hotel room for seven nights A rental car for six days that you will use when you visit the place Use the same rental car agency, airline, and hotel for all three time periods. Compare the three time periods and the three variables—hotel, car, and airline—that you used. Explain why the prices for each variable were different across the three time periods. I have done the top portion, but need help on why the prices are different between winter, summer and spring.

I used Priceline for my information.
