Frequently asked questions

Is it cheaper to buy a plane ticket from STL to Libertador General Jose de San Martin Airport (PSS) last minute?

If you'd rather play it safe, book well ahead of the date you want to leave. Don't forget that some of the biggest bargains can be found up to a year in advance. If your favorite carrier hasn't released tickets yet, check back regularly as offers are updated on Expedia constantly.
