Tenerife rarely appears on the radar of Midwest business travelers, which is precisely why the routing deserves attention: there is no nonstop option, and business class from Indianapolis to Tenerife requires a strategic connection through London, Madrid, or a German hub, with total journey time typically running well beyond the advertised ~8-hour flight segment once layovers are factored in. British Airways offers the most logical path, routing IND travelers through London Heathrow with a Club Suite product on the transatlantic leg—a proper door-closing suite with direct aisle access—before a shorter connection down to TFS on a narrowbody with Euro Traveller-style business seating, since BA doesn't deploy widebody metal on the Canary Islands leg. Iberia, as a fellow oneworld partner, provides a compelling alternative via Madrid, and I've found their connection times at Barajas Terminal 4S to be refreshingly efficient for a same-alliance transfer, with Iberia's A330 business class offering flat-bed comfort on the long haul before a quick hop to Tenerife South.
Lufthansa routes through Frankfurt or Munich, and while their long-haul business product (including Allegris on select aircraft) is excellent, the Canary Islands segment again reverts to a standard regional business cabin, so the real value lies in the transatlantic experience rather than the final approach into TFS. My insider tip: build in a minimum 2.5-hour connection window on any of these itineraries, since Canary Islands-bound flights from mainland European hubs often depart from remote gates requiring bus transfers, and misconnecting here means waiting for the next daily—not hourly—flight to Tenerife.
Seasonality favors the shoulder months of April, May, September, and October, when Tenerife's climate is ideal and premium fares tend to soften as leisure demand shifts elsewhere. Because pricing on this three-airline, multi-hub route fluctuates based on connection combinations and fuel surcharges from Spain and Germany, setting up automated fare alerts is the smartest way to catch a business class opportunity before it disappears.
