May is a popular month to fly from Miami (All Airports) (MIAA) to Lisbon due to warm transatlantic weather and spring events in Portugal. Expect slightly higher demand and increased early-booking fares; search for deals 6–10 weeks ahead. Consider flexible dates and mid-week departures for the best savings on Miami to Lisbon flights in May. Pack layers as Lisbon evenings can be cool despite daytime warmth. Major nearby cities and access points for departures include Fort Lauderdale, Hollywood, and Coral Gables for surface transport and alternate airport options.
Arrivals at Humberto Delgado Airport (LIS) in May benefit from spring weather, longer daylight hours, and an early tourist season vibe. Plan to use the Lisbon metro or Aerobus for efficient transfers to Baixa, Chiado, and Alfama. May sees increased international arrivals from the U.S., so expect moderate queues at immigration and baggage claim. Nearby major cities and accessible destinations include Sintra, Cascais, Porto (by short flight or train connection), and the Algarve for extended stays.
