How to book the cheapest flight to Illinois?
Scoring cheap flights to Illinois is as easy as booking with Orbitz. But if you’re eager to make sure you’re nabbing the best flight deals around, here are some tips your wallet will love:

  • Consider departing from or arriving at nearby airports to save extra cash. Enter your preferred departure and arrival airports in the form fields, then click on the ‘Nearby airports’ function below. It will list any available options.
  • Also, click on the ‘Show flexible dates’ link to see the prices for days around your chosen departure. You may be able to pick up cheaper flight deals if you’re flexible with your schedule.
  • To fine tune your results, click on ‘Show options.’ You can search based on airlines, seating class, and nonstop and refundable flights. You can also select your preferred departure and arrival times under ‘Sort & Filter’ to the left.
  • Once you know your travel dates, don’t delay booking your flight. Fares normally get more expensive as the departure date nears.
  • Save big on your vacation by bundling your flights, hotels and car rentals into an Orbitz package deal. Your budget will thank you.
  • Don’t travel during the busy season if you can. By steering clear of summer, school vacations and other popular dates, you can save plenty on your airfare.

What is the best time to book a flight to Illinois?
Reserve your seats to Illinois in January. This is the best month for low prices, closely followed by February and August. Snap up cheap flights and enjoy your dream getaway with Orbitz.

When it comes to cheap airfares to Illinois, the best days to make a booking are generally Tuesdays, Wednesdays and Saturdays. A rewarding flight deal is just clicks away with Orbitz.

Think about leaving early in the week to score cheap flights to Illinois. Orbitz data from 2020 indicates Monday is typically the most affordable day to head off, followed by Tuesday. Saturday was found to have the most expensive ticket prices. This is possibly because many passengers prefer to begin their trip after a long working week.

What do I need for the flight to Illinois?
The secret to a hassle-free flight is preparation. Listed below are some useful tips that’ll help get you ready for your journey:

  • Before you step on board the plane, you’ll need to show some type of government-issued ID, such as a passport. You’ll also need your boarding pass. If you’re traveling with children, check with your airline about which documents they require — if any.
  • Take some activities to keep you occupied on your trip to Illinois. Books and electronic devices like tablets and laptops will do the trick. Be sure to take a water bottle with you too. Even on a short flight, it’s important to stay well-hydrated.
  • It can get very cool on the plane. If you’d prefer not to shiver your way through the flight, wear an extra layer of clothes.

How do I get cheap first-class/business deals to Illinois?
There are ways of booking first or business-class fares to Illinois that won’t burn a hole through your savings. Pick up a seat in the pointy end of the plane for less with these helpful tips:

  • Be flexible. By being open to a range of travel dates, you’ll have a better chance of finding a deal on first or business-class airfares.
  • Budget airlines offer first or business-class seating at more affordable prices. Give the full-service carriers a miss and go with one of these cheaper options.
  • Take advantage of your airline’s customer loyalty program and use points to upgrade your seat. Alternatively, you can try bidding for an upgrade in online auctions.
