Southwest Airlines — the carrier built on a single aircraft type, no assigned seats and open seating for decades — is reportedly working toward flying Boeing 787s across the Atlantic, and it may have to add lie-flat business class to make the numbers work.

According to reporting picked up by View from the Wing, Southwest has contemplated dozens of 787s, potentially starting with leased or used aircraft to move faster. Six Boeing 787-9s from budget long-haul carrier Norse Atlantic have been floated, though Norse has also committed two of those jets to Pakistan International Airlines on wet lease. Airbus is pitching alternatives too: the A321XLR for thinner routes, the A330neo and the A220. Whatever the aircraft, this is years away — it requires a new pilot agreement covering widebody pay, rest facilities and long-haul scheduling, and talks have already been contentious.

The route logic is fairly clear. CEO Bob Jordan has named Baltimore as a natural gateway and suggested 8 to 12 long-haul destinations could cover most customer demand. Baltimore and Nashville lead the list of candidate hubs, with Austin, Las Vegas, Denver and Orlando also in the mix. One hard constraint: federal law bars long-haul flying from Dallas Love Field. London, Paris and Rome would likely be the first destinations, followed by Dublin, Barcelona and Amsterdam.

The awkward part is winter. Transatlantic demand collapses after summer, so Southwest would need somewhere to send widebodies — options include shifting capacity to Hawaii, South American cities like Buenos Aires and Santiago, or its Cancun hub. The economics are the deeper problem: long-haul, low-cost carriers have mostly failed, because fuel and aircraft costs dominate when the plane spends its day in the air. That's why analysts expect Southwest to build proper premium cabins — lie-flat business seats and possibly premium economy — plus the first-class-style product it already lacks domestically. Its first four lounges, in Austin, Baltimore, Honolulu and Nashville, hint at where this is heading.

Why should a traveller care? Because this would mean cheap-ish economy fares to London, Paris or Rome from cities like Baltimore, Nashville or Austin, with loyalty points to match — and a genuinely new premium option if the business class rumours land. It would also mark the final step in Southwest's transformation from the quirky domestic oddball into just another full-service global airline. For frequent flyers, that's either a win or the end of an era, depending on your view. Keep an eye on announcements over the next couple of years — the pieces are clearly moving.
