Japanese efficiency and really decent cost! Flew RT Narita-Sapporo Sept 2014 and loved it. English website that was understandable. Every employee super nice and since I was the only non-Japanese on the flight, did all the announcements in English as well as Japanese. No Frills and they mean it.
Use online check-in: Most lowcost airlines now offer passengers the possibility to check in online for their flight. In most cases you can check in online only if you have no hold luggage. However, some airlines do have a special bag-drop desk for passengers who wish to check in online and to take hold luggage with them. By checking in online, you will avoid queuing in order to check-in at the airport (and you will probably also save some money).
