All around a great location with incredible views. We stayed in a king suite on the 30th floor with views of both the city and lake thanks to architect that designed the building as a triangle that overlooks the Chicago river.

How much is a flight to Knox?

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.
  • Similarly, click on the 'Show flexible dates' option to view the prices for days around your selected departure. It's possible to score cheaper flight deals if your itinerary is flexible.
  • 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.
  • Whenever possible, avoid flying in high seasons. Airfares significantly increase during school breaks, summer and around other vacation times like Easter and Thanksgiving.

What is the best time to book a flight to Knox?
Book in January, February or August for competitively priced tickets to Knox. Once you've located a bargain, snap it up — cheap flights will appear and vanish in the click of a mouse.
What day of the week is the cheapest to book a flight to Knox?
In general, Tuesdays, Wednesdays and Saturdays are the cheapest days to book a flight to Knox. If you want unbeatable airfares, search across those days and you just might pick up a great flight deal.
What is the cheapest day of the week to fly to Knox?
According to Orbitz data from 2020, Monday is generally the best day of the week for cheap flights to Knox. Tuesday also offers wallet-friendly fares, while Saturday has the highest ticket prices. Although leaving at the weekend may be easier to organize, you'll have more cash in your pocket to play with if you take off earlier in the week.
What is the cheapest month to fly to Knox?
We won't keep you guessing — based on Orbitz data, August is generally the most inexpensive month to fly. Perfect for those who need a weekend getaway or simply escape from it all before the weather changes. The costliest time to fly is the height of summer, with airfares peaking in June.
Which airlines allow free cancellation?
Orbitz makes it a cinch to find carriers that offer flexibility. Simply select "Filter by flexible change policies" when searching for your flights and bada bing, bada boom! You'll see options that include free cancellation, no change fees and of course, the very best price.
What do I need for the flight to Knox?
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.
  • No matter the weather outside (or how long the flight), plane cabins can get a bit chilly. Bring a sweater on board to stop the goose bumps.

How do I get cheap first-class/business deals to Knox?
Smart travelers have a way of finding business or first-class flights to Knox without the steep price tag. Be like them with these helpful hints:

  • Be flexible. By being open to various travel dates, you'll have a better chance of spotting a sale on your airfares.

  • Bid for an upgrade in online auctions or upgrade your ticket with your frequent flyer points.
