When searching for a good deal, it’s best to be prepared for potential fluctuations in price. We recommend booking at least 10 days in advance, which can save you up to 141% on flights from Louisiana to Portugal compared to booking the week you need them. Waiting 10 days out may not be for everyone, so we have options available for flights within the next two weeks, with the lowest price starting at $559. For sooner than that we have options available in the next 3 days from $1,348.
Due to multiple factors, expect to potentially pay more when booking in June. For low rates, January can be a great choice for travel to Portugal. Flights to Portugal from Louisiana in January are about $1,130 on average during January, but can be found for as low as $587.
When flying from Louisiana to Portugal, the time of day you decide to fly out makes little to no difference towards the overall price you’ll pay on tickets.

I recently flew to Singapore on flight 21 April 28, 2024. From the time I was greeted at the aircraft door your cabin crew was warm welcoming, smiling and dressed sharped in their uniforms. I've flown around the world and this was my first time on singapore airline. Jason was very attentive to all of my needs. Kelly did made sure my food was correct and it was served at perfect temperature. Mohan check made sure i stayed hydrated they did a beautiful dinner service and lunch service. Everytime I went to the bathroom Ploy had my favorite drink ready. Even though I was in premium economy they gave us first class treatment. I truly enjoyed everything from start to finish on my flight. Even though this is the longest flight in the world I was thankful for the comfort your crew provided me in this journey. Having this amazing crew will surely bring me back on your airline for my vacation travel to Asia. Please give them a special thanks from me. These are memories I will cherish.
