Savannah's regional airport keeps things refreshingly simple, but the routing to Hannover requires a bit of strategy since there's no nonstop option: business class from Savannah to Hannover invariably means connecting through a major hub, with Atlanta-Delta, Charlotte or Philadelphia-American, or Newark/Chicago-United all viable gateways into Germany, typically via Frankfurt or Munich before the short hop north to HAJ. Delta's Atlanta connection is the one I'd favor most often, given the carrier's strong transatlantic widebody presence and Delta One suites on aircraft like the A330-900 or 767, which offer proper lie-flat comfort for the roughly eight-hour Atlanta-to-Frankfurt leg. American routes through Philadelphia or Charlotte onto its joint-venture partner British Airways or onto its own 777/787 Flagship Business seats, while United leans on its Polaris product out of Newark or Chicago, both solid choices depending on your home routing preference from SAV.
Having flown this corridor numerous times, my strongest recommendation is to build in a two-to-three hour connection window at whichever US hub you choose, since Savannah's smaller regional jets are notoriously vulnerable to minor delays that can cascade into missed transatlantic connections — arrive at your hub gateway with breathing room, and if given a choice, choose Atlanta in winter over Newark, where weather disruptions run higher. Frankfurt remains the more logical connection point over Munich for HAJ-bound travelers, since flight frequency to Hannover is better and immigration lines move faster if you're transiting rather than clearing at Frankfurt itself with a same-terminal connection. An insider trick: booking the Delta-Atlanta routing on Tuesdays or Wednesdays in shoulder months often unlocks better business class award availability than weekend departures, since corporate demand out of Atlanta thins mid-week.
Deal-wise, this Savannah-to-Hannover business class routing softens noticeably during January, February, March, and again in October and November, when both leisure and corporate transatlantic demand dips and premium cabins open up on partner award charts and revenue fares alike. Given the multiple airline and hub permutations at play here, setting up automated fare tracking for this specific city pair is genuinely the smartest way to catch the fleeting windows when premium fares dip into attractive territory.
