There is no nonstop path connecting Silicon Valley to the Algarve, which means booking business class from San Jose to Faro is inherently an exercise in routing strategy rather than a simple search. The most reliable answer, after years of piecing together this journey, is that Delta out of SJC connects efficiently through JFK or Atlanta onto a transatlantic partner, while TAP Portugal and British Airways offer the more elegant back halves of the trip via Lisbon and London respectively. My preferred combination remains Delta to JFK followed by a TAP Air Portugal A330neo in business class, since TAP's Lisbon hub feeds directly into short, frequent hops to Faro — a route TAP knows intimately as its own backyard.
The real craft here is choosing your connecting city wisely. Lisbon is the smarter overnight layover than London if your schedule allows, since TAP's business class lounge access and the short 45-minute Lisbon-Faro puddle jump make for a gentler final leg than fighting through Heathrow's Terminal 5 security lines before a British Airways Club Suite connection. If you do route through London, BA's Club Suite — with its closing door and reverse herringbone layout — is worth the extra connection time, and Heathrow's T5 offers a genuine business-class arrivals lounge for a shower and reset if you've got a long layover before the Faro hop. One insider trick: TAP frequently prices Lisbon stopovers of up to five days at no extra cost on business class tickets, letting you effectively add a Lisbon city break to a Faro-bound itinerary without paying for two separate trips.
Spring and early autumn — specifically April, May, September, and October — consistently deliver the best combination of fares and weather, since the Algarve's peak summer season inflates both leisure fares and demand for connecting flights. Given the multi-carrier routing required on this itinerary, fares can swing significantly week to week depending on which airline alliance is running promotions through JFK, London, or Lisbon, so setting up fare alerts for this specific SJC-FAO business class routing is the smartest way to catch a favorable window before it closes.
