American Airlines has some very low fares this week on routes competing with Frontier and Spirit Airlines sales. Another deal I see today is Los Angeles LAX to Denver DEN for $87 round trip or $44 one way. These fares are available for departures from August through November 18.
Fares rise to $79 one-way for winter season, which is still a great deal for Denver.

Fares rise to $79 one-way for winter season, which is still a great deal for Denver. Flying to Denver during the middle of ski season for under $175 round trip is another good fare.
