Montpellier's compact regional airport handles nothing wider than a turboprop, so anyone booking business class from West Palm Beach to Montpellier is really planning a two-leg journey through one of Europe's great connecting hubs. There is no nonstop option here: the realistic routing runs through Atlanta or JFK on Delta, then across the Atlantic to Paris, Amsterdam, or a European gateway, before a short regional hop down to Montpellier — total elapsed time hovers around 9.5 hours of pure air time, though door-to-door you should budget closer to 14-16 hours with the connection. Delta's transatlantic partnership with Air France means you'll often find yourself aboard an Air France A350 with their Business suite featuring a closing door, or a Delta One Suite on the transatlantic segment if routing through JFK, before transferring to an Air France regional jet into MPL. Lufthansa offers a compelling alternative via Frankfurt or Munich, particularly appealing now that Allegris cabins are rolling out on select long-haul aircraft, though availability on this specific configuration remains inconsistent, so I'd temper expectations rather than chase it specifically.
Having flown this corridor repeatedly for work tied to southern France, my strongest insider tip involves the connection at Paris CDG: always route through Terminal 2E if you're on Air France metal, and build in at least 90 minutes for the transfer to the Montpellier feeder flight, since immigration and security recheck can eat time unpredictably during summer peaks. Winter and shoulder-season travel — January through March, and again in October and November — consistently offers the best business class value on this routing, largely because leisure demand into the south of France collapses outside the Mediterranean summer season, while Delta and Air France still need to fill premium cabins on the core transatlantic trunk routes.
Because pricing on this three-airline, multi-hub routing fluctuates significantly week to week depending on which connection opens award or discounted business inventory first, it's worth setting up fare alerts specifically for the PBI-MPL city pair rather than shopping blind — that's the only way to catch the periodic dips before they disappear.
