No, Olpoi Airport (OLJ) does not have a lounge, so if you searched olpoi airport lounge or vanua lava airport lounge, the honest answer is that this small airstrip in Vanuatu's Torba province offers no dedicated waiting room, no counter service, and no seating beyond a basic open-sided shelter. It exists to move island residents and the occasional visitor on and off short domestic hops, not to hold travellers in comfort between flights, and nothing resembling a lounge, paid or complimentary, operates here.
What travellers actually do at Olpoi is straightforward: they arrive by boat or truck from villages around Vanua Lava, wait under the open shelter or in the shade of nearby trees, and board directly across the grass or gravel strip once the inbound aircraft, usually a small island-hopper, is visible on approach. There is no security screening lounge, no airline desk staffed between flights, and no food or drink service, so passengers bring their own water and snacks. Luggage is handled by hand across the strip rather than through any conveyor or check-in counter.
For anything resembling an airport lounge, the realistic destination is not Olpoi itself but Vanuatu's larger airports. Santo-Pekoa International Airport in Luganville, the country's second city, has a proper terminal building and a small cafe, though it is not known for a dedicated Priority Pass lounge either. Bauerfield International Airport in Port Vila, the national capital and Air Vanuatu's main hub, is the country's real aviation centre and the place where any lounge-style amenities, however modest by international standards, would actually be found.
If your itinerary routes through Olpoi on the way to or from a remote island stay, plan for a bare-bones wait rather than a lounge, and save any lounge-network membership for your connection through Port Vila or another hub further along your journey. Cyclone-season weather, roughly November to April, can also disrupt this kind of small grass or gravel strip, so build extra flexibility into your schedule around that period.
