✈️ Flight Guide: New York (Any) → Lisbon (LIS)

For transatlantic flights to Lisbon, New York (All Airports) (NYCA) travelers typically prefer John F. Kennedy International Airport (JFK) or Newark Liberty International Airport (EWR) because both offer seasonal nonstop flights to Lisbon Humberto Delgado Airport (LIS). LaGuardia (LGA) rarely has nonstop transatlantic services, so if you want the shortest travel time and fewer connections, search JFK or EWR departures. Compare fares and schedules across NYCA (All Airports) for October to find the best balance of price and convenience.

For travel in October, aim to book 6–10 weeks in advance to capture low-season or shoulder-season fares; monitoring prices in late summer often yields good deals. Use fare alerts, flexible-date search, and consider midweek departures (Tuesdays/Wednesdays) to find cheaper roundtrips. To grab last-minute October deals, check flash sales from carriers like TAP Air Portugal and United and set price alerts on Google Flights or Skyscanner.

October in Lisbon is mild with increasing chance of rain, so pack a light waterproof jacket, layers, and comfortable walking shoes for cobblestone streets. Bring a travel adaptor (Type F/E), a light sweater for cooler evenings, and a compact umbrella. Check airline carry-on limits and the seasonal weather forecast before you fly from NYCA to LIS to avoid surprises.

Arrive at least 3 hours before your international departure when flying from NYCA to LIS, especially during October when airports can be busier with fall travel and holiday surges around Columbus Day. Allow extra time for TSA checks, bag drop, and potential airport transfers between JFK, EWR, and LGA if connecting. Use online check-in to streamline your airport experience and reduce wait times.

In October, Europe ends daylight saving time on the last Sunday of the month while the U.S. changes later in November, so during late October the time difference between New York (All Airports) (NYCA) and Lisbon (LIS) can shift from 5 to 4 hours. This change can alter arrival local times and connection windows, so double-check scheduled arrival times and your phone's time zone settings when booking October flights. Confirm times with your airline to avoid missed connections due to DST changes.

As of October travel planning, entry and departure restrictions vary by airline and government policy; check both U.S. and Portuguese guidance before flying from NYCA to LIS.

For reliable updates, consult the U.S. State Department, Portugal’s health ministry, and your carrier prior to departure.

October in Lisbon brings mild temperatures (typically 15–23°C / 59–73°F) with increasing chances of rain late in the month, so plan outdoor activities earlier in the day.

Pack a light waterproof layer and flexible itinerary to accommodate brief showers while enjoying comfortable autumn sightseeing.
