United Airlines via ShermansTravel offers select United Airlines 1-Way Fares Nationwide with prices starting at $28.20. (On the ShermansTravel landing page, click on "United.com" in the top line to see this sale; although this sale only mentions specific routes, we found additional routes within.) That's tied with our mention from last week as an all-time low for any United Airlines flights. (It's also the best price we could find for select routes today by at least $32.) This price is valid on flights departing from San Francisco, CA, (SFO) with arrival in Las Vegas, NV, (LAS) on February 8. This travel deal is valid on fares through February 28.
