Four airlines cover this corridor well from Austin, each connecting through a different hub. British Airways routes via London Heathrow with its Club Suite product — a proper door, 1-2-1 configuration, and White Company bedding that makes the long sit through LHR worthwhile. Lufthansa connects through Frankfurt on its newer Allegris Business cabin, a lie-flat suite on the A350 with genuinely improved privacy over the old Lufthansa business seat. KLM funnels through Amsterdam with a straightforward 1-2-1 lie-flat cabin, Delft Blue houses on the tray, and generally reliable connection times to onward Turkish Airlines or KLM codeshares. Delta, meanwhile, routes through Atlanta or Minneapolis using the Delta One Suite — a closing door, Tumi amenity kit, and the advantage of a single-carrier itinerary from Austin all the way to Europe before interlining onward. For Austin to Dalaman business class travelers who want to minimize the number of separate airlines involved, Delta's ATL or MSP routing is often the smoothest on paper, though Lufthansa and BA give better connection banks into DLM during shoulder season.
