Departing from Houston (IAH) FAQs

Use price-tracking tools and flexible airport options (e.g., Porto or Faro nearby) to expand savings.

Arriving at Lisbon (LIS) FAQs

Airport taxes are usually included in the ticket price, but optional services and ancillary fees are paid separately.

December arrivals labeled ECON require early planning because holiday travel increases airport congestion and ancillary costs.

If flexibility is limited, consider a slightly higher fare that includes baggage or flexible change policies to avoid last-minute costs.
