NEW YORK (TheStreet) -- Shares of Southwest Airlines (LUV) - Get Report were rising in mid-afternoon trading on Thursday as the airline company increases fares across its domestic system by $5, CNBC reports.

JPMorgan upgraded shares of the Dallas-based company to "overweight" from "neutral" today with a $51.50 price target, the Fly notes.

The firm cited the fare hike and a recent decline in stock price as reason for the upgrade.

Additionally, the company reported mixed 2016 third quarter results yesterday, with revenue falling short of analysts' forecasts and earnings beating Wall Street estimates.
