Shannon to Tampa (SNN–TPA) — 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.

Uber and Lyft pickup is on the lower level curb; typically $20–30 to downtown Tampa and $45–60 to St. Petersburg. Taxis at the rank run $25–35 to Tampa center. The HART bus (Route 30X) connects to downtown for $2.25 but is infrequent; check schedules before relying on it.Rental car counters are in the arrivals hall with a shuttle to the consolidated rental facility. I-275 provides direct access north to downtown and south toward St. Pete. The airport's people mover system is free and connects all areas of the terminal complex.

Humid subtropical climate. Tampa is called the "lightning capital of North America." Afternoon thunderstorms are nearly daily from June through September, causing frequent ground stops and gate holds during summer afternoons. Summer afternoon flights routinely run late.

Hurricane season (June–November) poses storm surge and wind risk. Direct hits are rare, but evacuations periodically affect the region. Winter (December–February) is mild at 14–23°C with very low disruption risk. Spring (March–May) is the most comfortable season.
