Frequently asked questions

Is it cheaper to buy a plane ticket from Northwest Arkansas National Airport to Posadas Airport last minute?
Being a spontaneous soul is a fantastic way to discover the world, but it's not always the best method to score a cheap airfare. It's better to book your Northwest Arkansas National Airport to Libertador General Jose de San Martin Airport (PSS) trip well in advance instead of leaving it till the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. We recommend saving that spontaneity for when you reach your destination!
Can I change the date of my flight from Northwest Arkansas Regional Airport (XNA) to Posadas Airport?
You can make changes to your Northwest Arkansas Regional Airport (XNA) to Posadas Airport trip through the Expedia Trips portal. But before doing so, read the rules and restrictions in your itinerary to learn what you're allowed to do and what fees apply for changes.
