SFO to Chicago $197 AA, UA, VX or $178 Frontier

Chicago has been one of the primary battlegrounds for cheap airline fares in 2015. Airlines are blasting away at fares on Chicago routes in a competition for control of the skies over this city, reminiscent of the mob battles fighting for supremacy of Chicago’s streets in the roaring 20s. Fares have been so low on California to Chicago routes that $178 looks like extortion racketeering for consumers.

Round trip tickets were as low as $30 and $40 round trip on Frontier and under $100 on American and United in August. Two weeks ago fares were around $116 round trip on American.

There are not too many places east of the Mississippi you can fly for under $200 from California when booking tickets most days. Chicago is the hotbed of cutthroat competition between low cost carriers and the legacy airlines.

Frontier Airlines has the low fare today at $178 for SFO-ORD and most availability. The big deal is this is available for nonstop flights. No stopover in Denver required.

American, United and Virgin America all have $197 nonstop flights. These fares tend to be lowest for weekday travel.

Spirit Airlines has the overall lowest base fare for Oakland flights at $137 to $177 on many dates for OAK-ORD.

Departure Dates: Low fares are available for nearly every day of the week. If a round trip is high for your specific dates, there are good opportunities to get most dates priced low by flying one way on one airline and return on a different airline with two one-way tickets.

  1. Both Spirit & Frontier have really ramped up their flight schedules from Chicago. A few years ago they only had a few flights each but now they both serve a ton of new destinations. You couldn’t PAY ME to fly either one of them, but i do love the fare wars they’ve sparked from Chicago!
