Charted: Southwest's new plan

Southwest Airlines just delivered its "most transformational plan" ever to investors, promising to juice its profits over the next three years.

Driving the news: Southwest predicts the three-year plan will add $4 billion to its earnings before interest and taxes in 2027.

• It's built around new revenue streams, such as charging for perks and new partnerships with international carriers, and new ways to lower and manage costs.

A couple of other crowd pleasers were disclosed as well:

• The airline raised its forecast for RASM (a measure of how much revenue an airline generates for each available seat) in Q3 to 2%–3% growth, from its prior estimate of flat to down 2%.
• It also disclosed a new $2.5 billion share repurchase program.

The impact: Shares closed up 5.4% today, to $29.93.

Yes, but: Activist investor Elliott Management was not impressed, calling the investor day "another promise of a better tomorrow from the same people who have created the problems we face today."

• It's expected to call a special meeting for Southwest shareholders to vote on its own slate of directors as soon as next week.
