1. The cheapest day to fly from Chicago to Las Vegas is on a Tuesday, saving up to $35

While the weekend seems like an ideal time to visit Vegas, Sin City really never sleeps. If your schedule allows, departing from Chicago to Las Vegas on a Tuesday could save you up to $35. That could be better spent on a round or two of poker. Win some (or a lot of) money, and you are looking at a possible room upgrade at your Vegas hotel. After all, this is Vegas. Anything’s possible!

2. Save up to $52 by returning on a Wednesday

Playing well? If you find yourself on a roll (so to speak) in Vegas, you may want to extend your stay. Plan your flight home on a Wednesday, and you could save up to $52. That may be chump change to a high roller, but it is also the equivalent of a delicious meal at one of Las Vegas’ popular celebrity-chef restaurants. For instance, pecan-crusted redfish is only $37 at Emeril’s New Orleans Fish House. Order that, and you’ll still have money for dessert — that is, if you still have the appetite for it.

3. The cheapest time to book a flight from Chicago to Las Vegas is 21 days in advance, saving up to $300

While a last-minute weekend getaway may be exactly what you need, you can save up to $300 by booking 21 days in advance. Prices rise dramatically if you wait to book a flight until 10 days or less in advance. Plus, you’ll want to save money so you can make sure to get the full Vegas experience while you’re visiting. Blackjack hands and several shots of tequila don’t exactly come cheap in Sin City.

4. The cheapest time to fly from Chicago to Las Vegas is in January, saving up to $50

While traveling in January can be tiring, especially in Chicago when winter temperatures reach below zero, you can save up to $50 doing so. Plus, traveling to a warmer destination like Vegas is sure to appeal to those Chicagoans looking to escape the snow and ice. Prices are better than in August or October when ticket prices to Vegas reach above $300, and temperatures are milder than the scorching desert heat at the end of a Vegas summer.

5. Fly out of O’Hare (ORD) for the best deals

Flights out of O’Hare International Airport average about $284, which is why flying out of this Chicago airport offers the best deals. A flight out of Midway International Airport is about $40 more on average. Use that $40 towards a ride on the Stratosphere’s Big Shot. The ride, located atop the hotel, takes passengers to a height of 1,149 feet above The Strip before dropping them 160 feet at 45 mph. Be prepared for your stomach to drop while catching some of Sin City’s best views.

6. American has the cheapest direct flights from Chicago to Las Vegas

Compared to other airlines, American Airlines offers the best deals on non-stop flights from Chicago to Las Vegas. While prices are about $50 more than some Spirit Airlines flights, Spirit Airlines has several hidden fees that passengers will have to pay at time of departure. For instance, Spirit passengers have to pay $35 each way for any type of luggage apart from a small personal item that can fit under the seat in front of them. American, on the other hand, allows for customers to have a carry-on and a personal item, free of charge.

Airlines offering direct flights from Chicago to Las Vegas:- Spirit makes the journey in 3.75 hours for $279 round trip, on average.- American makes the journey in 4 hours for $336 round trip, on average.- United makes the journey in 4 hours for $345 round trip, on average.

Airlines offering connecting flights from Chicago to Las Vegas:- Frontier makes the journey in 6.5 hours via Denver for $300 round trip, on average.- Delta makes the journey in 5.5 hours via Minneapolis for $391 round trip, on average.

7. Frequent fliers on American can use 25,000 miles to book a round-trip ticket

If you fly American frequently, which is likely for Chicagoans since O’Hare is a hub for the airline, then you can use your miles to book a flight to Vegas. About 25,000 miles can get you a round-trip ticket from Chicago to Las Vegas. It’s a good destination to spend your frequent flier miles on because direct flights between the two occur frequently. That means in less than four hours, you can be attending a Cirque du Soleil show, being entertained by some of the world’s best acrobats.
