Yeah, flying in J w/ AY from HEL is currently a "strictly onboard" experience. At the airport, the only "perk" you get is the priority check-in. So, the question you need to ask yourself is would you upgrade your flight for the onboard experience? If the answer for that is yes, then go ahead, as in J it is pretty much the same as pre-COVID (minus the possibility to choose from different meal options).
