United has matched last week's Southwest sale with a nearly identical sale of their own. If you prefer to fly out of major airports like Chicago-O'hare, Houston-Intercontinental, or Washington-Dulles, this sale may be what you're looking for. You may find that American and/or Delta will be matching along some routes as well.

Travel is valid on Tuesdays, Wednesdays, and Saturdays through June 13, 2018, with a 21-day advance purchase required. Avoid blackout dates on May 24, 25, & 28. A Saturday night stay may be required depending on the route.

Tickets must be booked by March 8, 2018.

Nonstop Fares include:

San Francisco to Reno $167 round-trip

Los Angeles to Reno $183 round-trip

Chicago to Norfolk $193 round-trip

Spokane to San Francisco $197 round-trip

Houston to Oklahoma City $201 round-trip

There are many more routes and these fares all work in reverse as well. Prices are for basic economy and only include one small personal item (small backpack, purse, etc.). Larger carry-on bags are not allowed. Checked bag fees start at $25 each way. If you would like to bring a larger carry-on bag, consider the higher regular economy price.
