Estonia's crisp Hanseatic charm sits at the far edge of a journey that demands careful routing, since no carrier offers business class from West Palm Beach to Tallinn on a single ticket without a transatlantic connection. The practical answer: fly American Airlines or Delta from PBI to a major hub—Miami, JFK, or Boston—then connect onto Finnair, whose A350 business class and signature "Nordic Sky" service via Helsinki remains the most sensible gateway into the Baltics. Finnair's Helsinki hub is genuinely the linchpin here; its short 80-minute hop to Tallinn on a regional jet makes the final leg painless after a long-haul crossing, and Helsinki Airport's business lounges are efficient enough that even a tight connection rarely feels rushed.
Having routed this itinerary numerous times, I've found the AA/Delta domestic legs matter more than travelers assume—American's PBI-to-Charlotte-or-JFK connections tend to run more reliably in shoulder season than Delta's Atlanta routings, which can bunch up with summer thunderstorm delays. Once aboard Finnair's transatlantic long-haul, the A350's business seats offer direct aisle access and a clean, minimalist Nordic design that suits travelers who prefer function over flash. My insider tip: book the AY transatlantic segment with enough buffer—at least two hours—at Helsinki, because immigration lines can swell unpredictably when multiple wide-bodies land in a tight window from Asia and North America simultaneously, something not obvious from the schedule alone.
May through September remains the sweet spot for this itinerary, both for Baltic weather and for finding decent business class award or paid space on the Helsinki-Tallinn connection, which fills quickly with cruise passengers in high summer. Because pricing on mixed AA/Finnair itineraries fluctuates with both domestic and transatlantic demand cycles, setting up fare alerts across these carrier combinations is the smartest way to catch a favorable window before Baltic summer demand tightens availability.
