Five carriers compete for this Miami to Tenerife business class market, each routing you differently. American Airlines uses its Flagship Suite on the transatlantic leg — a proper lie-flat suite in 1-2-1 configuration with Casper bedding and Flagship Lounge access if you're connecting through a hub like Philadelphia or JFK. British Airways offers the Club Suite, which adds a closing door for genuine privacy, plus White Company linens; connections typically run through London before a short hop down to Tenerife South. Lufthansa's newer Allegris suites, found on select A350s, bring German engineering to the cabin with excellent seat ergonomics and a Frankfurt or Munich connection. Iberia is the natural choice given its Madrid hub sits almost directly on the way to the Canary Islands — expect strong Spanish wine lists and jamón-forward service, plus a short final leg. Turkish Airlines routes through Istanbul, and while it's the longest connection geographically, DO&CO catering and the Istanbul lounge (one of the more impressive airport lounges anywhere) make the detour worthwhile for many travelers.
