For a long time, business class was akin to economy with larger seats and more seat pitch (space for your legs), but the continuing drive to strip all frills out of economy and better other airlines’ business classes has seen some major changes in the past decade.
At the airport, business class flyers typically have a separate check-in area or at least their own row, and can access a discount on business class tickets that offers drinks, snacks, newspapers and maybe Internet access. Some of the best lounges offer showers and even nap rooms. Note that you can typically only use a business class lounge at your departure airport and when waiting for a connection, although some airlines allow long-haul passengers to use them on arrival as well.
