Shannon to Los Angeles (SNN–LAX) — Airlines, Schedules & Connections

Irish passport holders enter the United States visa-free under the Visa Waiver Program (VWP) for stays up to 90 days. An approved ESTA (Electronic System for Travel Authorization) is required before boarding. The ESTA costs $21, is valid for 2 years or until the passport expires (whichever comes first), and covers multiple entries. Apply at esta.cbp.dhs.gov at least 72 hours before departure, though most approvals come within minutes.

Passport must be an ePassport (biometric chip, all current Irish passports qualify). No supporting documents are formally required for ESTA approval, but CBP officers at the port of entry may ask for proof of onward travel, accommodation details, and sufficient funds. The 90-day VWP stay cannot be extended and does not allow a change of immigration status. If you need more than 90 days, apply for a B-1/B-2 visa at the US Embassy in Dublin (MRV fee $185, interview wait times vary from 1 to 6 weeks).

Direct flights from Dublin to the US serve New York (JFK/EWR), Boston, Chicago, Washington Dulles, Los Angeles, San Francisco, and several others, running 7 to 10 hours. Shannon also has direct US routes. US Customs and Border Protection preclearance operates at Dublin and Shannon, meaning you clear US immigration before boarding and arrive as a domestic passenger. The US dollar is the only currency. No vaccination requirements for Irish arrivals.

LAX has no direct rail link to downtown. The closest option is the free LAX Shuttle G to the Metro C Line station at Aviation/Century Blvd (fare $1.75 to Union Station, 40–50 min). Taxis use a meter; expect $35–55 to downtown and $30–45 to Santa Monica. Ride-shares cost $20–45 depending on destination and surge pricing.Rental car facilities are a short shuttle ride from terminals. FlyAway buses run to Union Station, Van Nuys, Hollywood, and Westwood ($9.75–11.25). For LAX Connect (the new people mover to Inglewood), check if it has opened at time of travel.

Mediterranean climate. Summers are warm and dry (24–30°C) with low humidity and almost no rain. Winters are mild (10–18°C) with occasional rain from November through March. Fog ("June Gloom") is common from late May through July, blanketing mornings until noon and causing departure delays.

Santa Ana winds occur in fall and spring, sometimes grounding departures briefly. Heat waves in September–October can push temperatures above 38°C inland, though LAX itself stays cooler near the coast.
