Don't expect widespread sales or cheap flights home for Thanksgiving. But a number of cities are seeing ridiculously low prices at off-peak hours — prices the industry has spent the years trying to eliminate.
Fliers have been able to fly Chicago to Boston for $80 roundtrip, San Francisco to Las Vegas for $67 roundtrip and New York to Los Angeles, with a connection, for $150 roundtrip.
"This is the big break consumers have been waiting for in response to lower fuel prices," says Seth Kaplan, managing partner of industry newsletter Airline Weekly.
The price of oil is at the lowest level in six and a half years and the industry is saving billions of dollars on fuel, giving airlines leeway to cut fares but still post healthy profits. Airlines have also added larger, more efficient planes to their fleets while packing more seats into existing jets. So, while the number of domestic flights is down slightly over the past 12 months, there are now 3.4 percent more seats for sale — too many to meet the demand in all cities. To fill those extra seats, airlines have had to offer discounts.
Still, airlines are being very selective. Forget finding a deal for busy holidays or on Mondays, Thursdays and Fridays when business travelers fly. The best prices are for flights on traditionally slow days like Tuesday, Wednesday and Saturday. And it helps if Southwest Airlines, Spirit Airlines or Frontier Airlines flies the route.

For instance, Frontier recently had a sale for members of its club who pay an annual $50 fee. Tickets were being offered for $15 one-way including taxes.
American Airlines and — to a lesser extent — Delta Air Lines and United Airlines are matching some of the discount fares. By doing so, they actually undercut the ultra-low-cost carries because Spirit and Frontier charge customers extra to use overhead baggage bins or to have a drink of water.
"They're trying to force them out of the market and they have the power to do this because they are making record profits," says George Hobica, founder of travel deal site AirfareWatchdog.com
