Montpellier's compact regional airport has no meaningful long-haul service, which is precisely why routing strategy matters more on this itinerary than the actual cabin you choose. There is no nonstop option for business class from Indianapolis to Montpellier — every itinerary connects through a major European or domestic hub, and after dozens of trips through this corridor, I've settled on Paris via Delta/Air France or Frankfurt via Lufthansa as the two most reliable paths. Delta and Air France codeshare extensively out of Indianapolis, typically routing through Detroit or JFK before the transatlantic hop to Paris-Charles de Gaulle, where Air France's La Première and Business cabins on the A350 offer some of the better long-haul seats in the sky, followed by a short Air France or low-cost regional connector down to Montpellier. Lufthansa's alternative via Frankfurt puts you in their newer Allegris business seats on select 787 and A350 routes, with the German hub offering faster minimum connection times than CDG if your Indianapolis departure runs late.
The Frankfurt routing tends to reward efficiency-minded travelers — Lufthansa's Terminal 1 layout makes tight connections more manageable than CDG's sprawling Terminal 2E, especially if you're arriving internationally and need to clear a security recheck. My insider tip: book the Montpellier feeder flight as a separate short-haul segment with at least a 2.5-hour buffer in Paris or Frankfurt, since regional connections to MPL sometimes get consolidated with little notice during shoulder season, and having buffer protects your business class booking from a missed-connection scramble. Air France's seasonal capacity into southern France also dips in summer, when carriers redirect regional aircraft to more heavily trafficked Mediterranean leisure routes, so travelers chasing premium cabins should lean toward the January-through-March and October-November windows, when both award space and paid business fares loosen up considerably.
Montpellier's appeal — its wine country proximity, Roman heritage, and less-trampled Mediterranean coastline — makes the extra connection worthwhile, but the fare volatility on this route rewards patience and vigilance rather than snap decisions. Because pricing on Indianapolis-to-Montpellier business class itineraries can swing significantly based on which hub carrier is running a seasonal promotion, I'd strongly recommend setting up automated fare alerts rather than manually checking, so you catch the pricing dips the moment they surface.
