There's no such thing as a simple hop from T.F. Green to the Aegean, and that's precisely what makes routing intelligence so valuable here. Since Providence lacks any long-haul widebody service, business class from Providence to Mykonos always involves a domestic or transatlantic connection paired with a final leg on Aegean Airlines' Airbus A320 fleet into JMK's compact seasonal airport — a fact worth stating plainly: there is no nonstop option, and JMK itself only handles narrowbody aircraft, so your premium cabin experience will be found on the long-haul segment rather than the island landing. My preferred build is PVD–London Heathrow on British Airways, transferring to Athens, then a short Aegean hop to Mykonos. British Airways' Club Suite, now rolling out across more 777 and A350 routes from Heathrow, offers a proper door and direct aisle access — a meaningful upgrade over the older Club World cabin, so it's worth checking your aircraft type before booking. Lufthansa via Frankfurt or Munich into Athens is the other strong contender, and if you can secure their new Allegris business class (still expanding across the fleet), it's genuinely one of the best hard products flying the Atlantic right now.
Athens is the pivot point either way, and I always build in a three-hour buffer there — Aegean's connections to the islands are efficient, but Athens airport's distance from the city means arriving passengers should resist the urge to dash out for a quick ouzo between flights. Fly into Mykonos before mid-June or after early September and you'll dodge both the punishing midsummer heat and the airport's peak congestion, which turns the tiny terminal into a logjam of yacht charterers and wedding parties. My insider tip: Aegean's business class on the Athens–Mykonos hop is often a paid upsell rather than a confirmable award seat, so book that segment separately and early, since inventory disappears fast in high season regardless of what class you're flying upstream.
April, May, September, and October remain the sweet spot for both fares and island weather, but premium inventory across BA, Lufthansa, and Aegean shifts unpredictably given the route's heavy reliance on connections — which is exactly why serious travelers on this itinerary set up fare tracking rather than checking manually, letting alerts do the work of catching the rare moments when business class pricing dips into reasonable territory.
