When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 55 days in advance, which can save you up to 169% on flights from San Antonio to Portugal compared to booking the week you need them.

For sooner than that we have options available in the next 3 days from $1,722.
Due to multiple factors, expect to potentially pay more when booking in June. For low rates, February can be a great choice for travel to Portugal. Flights to Portugal from San Antonio in February are about $1,184 on average during February, but can be found for as low as $640.

Bad experience with the staff boarding the gate. I couldn’t board with my carry on, personal item and a funny bag. I had to put my passport inside my pockets and put the funny bag inside the personal item. Then after passing the staff pull out everything again.
