Nice hotel. Great location. Nice room. Pictures made hotel seem like it was so much more. It was just one small hallway. Nothing more. Very disappointed with the lobby. I thought by the pictures I was getting so much more! Payed a $150 resort fee for two night. There was absolutely no resort and no resort benefits. That was purely a money grab. Didn’t even get my room cleaned each day. Nice room. Nice hotel. Just less that I thought!

How to book the cheapest flight to Knox?
Landing cheap flights to Knox is as easy as booking your ticket with Orbitz. But if you’d like to make sure you’re walking away with the best flight deals around, here are a few tips to keep your wallet happy:

  • Depending on your departure point, click on the ‘Nearby airports’ function (located under the departure and arrival options). Sometimes, alternative departure points offer more value for money.

  • You can also select the ‘Show options’ function to filter results for your preferred airline, seating class, nonstop flights and refundable flights. Under ‘Sort & Filter’ to the left, you can even pick the time of day you’d prefer to fly.
  • Book your fare as soon as you know your travel dates. While you can get lucky on occasion, airfares rarely fall in price as your departure date gets closer.
  • Consider combining your flights, hotels and car rentals into an Orbitz package deal to save cash.

Flying can be a joy with a bit of pre-planning! Make your journey a hassle-free one with the following handy hints:

  • Before you step on to the plane, you’ll need to present a valid form of government ID, such as your passport. You’ll also need your boarding pass. If you’re traveling with children, check with your airline about which documents they may need.
  • To keep you busy on the short hop to Knox, download your favorite songs or restock the audiobook library on your smartphone. Food can also be a welcome distraction while in the air, so take some snacks.
