Tickets from $527 both ways. Checked baggage is not included in the base fare.

✈️ Air France — AFR 58/100 (premium-light-elite)
In this fare:
  • Checked baggage: Not included — paid checked baggage extra
  • Onboard meal: Hot meal
  • WiFi: Free wifi (members only)
  • Cabin: 31″ pitch on Boeing 777 / 787
✈️ Operated by Delta Air Lines. This fare is sold by Air France, but only Porto–Paris (AF1517) is flown on Air France metal. Detroit–New York (AF8586), New York–Porto (AF3599) and Paris–Detroit (AF3550) are operated by Delta, so the aircraft, cabin, meal and Wi-Fi on both transatlantic legs are Delta’s own product, not Air France’s — they may differ from the Air France details above. The outbound connects in New York (JFK); the return connects in Paris (CDG).

🌍 About Porto
Porto's signature dish is the francesinha: a brick of toasted bread layered with steak, ham, and sausage, blanketed in melted cheese and drowned in a spiced tomato-and-beer sauce, fries on the side. Order it once, share it, and don't plan much after. The thing most people get wrong: the port wine lodges aren't in Porto at all — they're across the Douro in Vila Nova de Gaia, a short walk over the Dom Luís I bridge, and the tastings are there. Come in June: it's the warmest, driest month with crowds still manageable, and the May and September shoulders are nearly as good. Skip December through February unless cheap fares tempt you — Porto's winter is genuinely wet, rainier than most of northern Europe, not just grey.
