We recommend that you use Google Flights to find dates to fly, then book through an online travel agency, such as Orbitz, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz’s courtesy cancellation if you’re unable to travel. Additionally, keep in mind that discounted partner fares may not earn miles with US-based carriers.United is attacking American’s fares on many domestic routes out of the airline’s contested Chicago hub. Fares from Chicago (and vice versa) to Los Angeles (LAX), New York (LGA), San Diego (SAN), Boston (BOS), Dallas (DFW), and other cities are available starting $76 round-trip, or $70 for a same-day turn. Fares are available for mostly weekday departures from September until November. This could make for a good segment or mileage run if you need more flights to qualify for elite status next year.Airline: UnitedRoute: Chicago (ORD) to many US CitiesCost: $76+ round-trip in economyDates: September 2016 - November 2016Booking Link: OrbitzPay With: American Express Premier Rewards Gold, Citi Prestige or Chase Sapphire PreferredHere are a few examples of what you can book:Chicago (ORD) to New York (LGA) for $76 round-trip in November:Chicago (ORD) to New York (LGA) for $76 round-trip in November.Chicago (ORD) to Los Angeles (LAX) for $80 round-trip in November:Chicago (ORD) to Los Angeles (LAX) for $80 round-trip in November.Chicago (ORD) to Dallas (DFW) for $76 round-trip in November:Chicago (ORD) to Dallas (DFW) for $76 round-trip in November.Maximize Your PurchaseSign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
