Japanese LCC with a decent English language website. Allowed me to book and pay for the flights from overseas while there was a seat sale. Managed to get good fares for return Tokyo to Sapporo flights. Their Skip service is really convenient allowing you to forego the usual check in procedures and instead proceed to check baggage and security screening with the 2D barcode provided. At both Haneda and Chitose airports though, the ANA bag drop counters also served the Air Do flights. As there are a lot of ANA counters, it can get confusing which one to use for our Air Do flight. After consulting with helpful ground crew, managed to do so relatively swiftly. The plane seemed to be an old model but appeared well maintained. Free drinks were served but the limited meal selection were meant for purchase. A good experience flying Air Do for the first time.
