There's something quietly satisfying about routing through Atlanta rather than the more obvious New York gateways when you're heading toward the Algarve, and it's why savvy Savannah travelers have made this their default itinerary. There is no nonstop option for business class from Savannah to Faro, so the real work lies in choosing the right connection: Delta out of Atlanta, where the Delta One suite on widebody transatlantic equipment gets you into Lisbon or a European hub with sliding doors and proper lie-flat comfort, or a British Airways routing through London that lands you in the Club Suite, BA's forward-facing pod with a door of its own. TAP Air Portugal is the other logical piece of this puzzle, and its strength is Lisbon: once you're across the Atlantic, TAP's short intra-European hop down to Faro is quick and simple, making a Delta-to-TAP or BA-to-TAP combination the most sensible construction for this route.
Having flown this corridor repeatedly, my strong preference is routing through Lisbon rather than London when connecting onward to Faro — TAP's Lisbon hub is compact and connections are typically smoother than fighting through Heathrow's T5 with a short layover. If you go the BA way, budget extra buffer time at Heathrow, as Club Suite is excellent but T5 connections to Iberia partners can feel rushed. Savannah's own airport is refreshingly stress-free, so arrive with a normal cushion rather than the padded hours you'd want at a mega-hub. Seasonally, April, May, September, and October are the sweet spot — before and after the Algarve's peak summer crush, when premium cabin space opens up and Delta and TAP both tend to loosen award and revenue inventory.
One insider trick: TAP occasionally releases business class saver space on the Lisbon–Faro leg even when the transatlantic segment is priced normally, so pricing the two segments separately before booking as a single itinerary can occasionally surface savings that a single search won't show. Given how much these fares swing month to month across three very different carriers, setting up dedicated fare alerts for this specific Savannah-to-Faro pairing is the smartest way to catch the window when premium seats dip.
