  • Consider departing from or arriving at nearby airports to save on your airfare. Enter your preferred departure and arrival points in the form fields, then click on the 'Nearby airports' function below. It will list your options, if any.
  • Similarly, click on the 'Show flexible dates' link to see the prices on days either side of your selected departure. You may be able to score cheaper flight deals if you're flexible with your dates.
  • You can also use the 'Show options' link to filter results for your preferred airline, seating class, nonstop flights and refundable flights. Under 'Sort & Filter' to the left, you can even choose the time of day you'd like to fly.

  • Combine your flights, hotels and car rental into a package deal and enjoy discounts. Save your dollars for things you're really excited about, like exploring every corner of Mercer County.

  • A properly packed carry-on bag is just the ticket for a great flight experience. Given your flight to Mercer County is no short hop, take enough snacks and activities to keep you happy. Something to read is sure to help the hours pass.
