For the cheapest international flights from the USA: target shoulder-season weeks (mid-January, mid-April, late October), fly mid-week, and prefer one-stop itineraries via Reykjavík, Istanbul or Lisbon — frequently $300–$500 cheaper than nonstops.
International flights have far more pricing variance than domestic. Knowing the patterns saves a lot.

Cheapest-Gateway Tactics
If you have driving flexibility, the cheapest US gateway varies wildly by destination:

- To Asia: LAX, SFO, SEA dominate Trans-Pacific pricing
- To Latin America: MIA, IAH, MCO are cheapest
- To Australia/NZ: LAX, SFO, DFW

- TAP via Lisbon — to Europe and Africa
- Turkish via Istanbul — to Europe, Middle East, Asia, Africa
- Aer Lingus via Dublin — to UK and continental Europe
- Air Canada via Toronto/Montreal — to Europe and India
