Southwest Airlines (WN, Dallas Love Field) is reportedly leaning toward the Boeing B787 family as it ponders launching long-haul international flights, according to three people familiar with the carrier’s fleet planning. If an order is placed, it would break away from Southwest’s long-held business model of operating exclusively narrowbody B737 jets. However, no final aircraft decision has been made, and the choice ultimately rests with the company's board. Southwest Airlines operates a fleet of 823 aircraft, comprising 290 B737-700s, 343 B737-8s, and 190 B737-800s.
