Legacy carriers $($e$.$g$.,$ Delta$)$ tend to score fairly high among most competitive elements in the airline industry, including different seating class choices $($such as business class, economy comfort, basic economy, and so on$)$; in$-$flight amenities such as Wi$-$Fi$,$ personal video console to view movies or play games, complimentary drinks and meals; coast$-$to$-$coast coverage via connecting hubs; plush airport lounges; international routes and global coverage. In contrast, the low$-$cost airlines $($e$.$g$.,$ SWA$)$ tend to hover near the bottom of the strategy canvas, indicating low scores along a number of competitive factors in the industry, with no assigned seating, no in$-$flight amenities, no drinks or meals, no airport lounges, few if any international routes. A relatively lower cost structure goes along with a generic low$-$cost leadership strategy. Now look at JetBlue$$s value curve.
