# The 'Cheapest Entry Point' Strategy
Don't just book a flight to your final destination (e.g., Rome or Athens). It is often $200-$400 cheaper to fly into a major "Gateway City" and take a cheap flight (Ryanair/EasyJet) or train to your final stop.
Top 3 Gateway Cities in 2025:
- London (LHR/LGW): Huge volume of flights from NYC/BOS/LAX keeps prices low.
- Dublin (DUB): Aer Lingus offers great deals and you clear US customs in Dublin on the way back!
- Lisbon (LIS): TAP Air Portugal often has the cheapest fares from the East Coast and Miami.

# Traveler Tips for US-Europe
The "Open Jaw" Ticket
Don't backtrack. Fly into London and out of Paris. It usually costs the same as a roundtrip and saves you a day of travel.
