HA does not have online check-in, correct. Nada. None. No OLCI for int'l flights. Even for J, the line at the airport in HNL can be slow and long. (Really ridiculous how HA is so backwards in technology that it can't figure out how to do OLCI or provide any meaningful online self-service. HA is still stuck in the 1980s...)
Separately, I have a question along this same general topic. On a JL+HA itinerary, where JL is the first flight, will the JL OLCI also provide the connecting HA flight boarding pass? Anyone have experience with that?
