Why Did Direct Aisle Access Become The Standard In Long-Haul Business Class?

Today, most legacy carriers offer luxurious business class cabins that elevate the in-flight experience beyond what was previously realized in premium cabins. Services that do not offer direct aisle access are seen as outdated, but plenty of airlines still fly such configurations. For example, Lufthansa’s old business class is still offered on the airline’s A340s, and United’s old business class is still offered on Boeing 777-200s.
