Legoland's headquarters city isn't exactly a hub anyone flies to on a whim, and that's precisely what makes routing intelligently so important. There's no nonstop option for business class from Raleigh to Billund, so the real decision happens at the connection point: SAS routes through Copenhagen, Lufthansa through Frankfurt or Munich, and KLM through Amsterdam, with Copenhagen being the most logical gateway since Billund is only a short domestic hop or scenic drive across Jutland from there. In practice, I've found the SAS connection via Copenhagen the smoothest for this itinerary, minimizing the layover friction that can wear down even seasoned travelers after a long transatlantic haul from RDU.
On the transatlantic leg, expect widebody business class products that have genuinely improved in recent years. SAS's A330 and A350 business class cabins offer direct aisle access and comfortable flat-bed seating that suits the roughly eight-hour crossing well, while Lufthansa's mix of older 747-8 and 340 configurations alongside newer Allegris-equipped aircraft on select frankfurt routes can vary noticeably in quality — it's worth checking your specific aircraft type before booking. KLM's World Business Class on its 787 and A330 fleet remains a dependable, if understated, choice, particularly for those connecting through Schiphol's efficient transfer process. My insider tip: if you're routing through Copenhagen on SAS, build in at least a 90-minute buffer, since immigration and the connection to the Billund puddle-jumper can bottleneck during peak Danish summer tourist season, especially with Legoland traffic swelling June through August.
Late spring through early fall — May through September — consistently offers the best combination of fare value and schedule reliability on this corridor, as European carriers ramp up capacity to meet leisure demand. Because fares on this three-carrier route fluctuate based on connection city and seasonal competition between SAS, Lufthansa, and KLM, setting up automated fare alerts is the smartest way to catch a premium-cabin deal before it disappears.
