About This Route
394 business award seats seen here in the last 7 days (last verified 1hr ago). As with São Paulo, LATAM is the carrier that produces on this route. Buenos Aires is a long sector — over eleven hours from Miami — and LATAM operates it with a lie-flat business cabin. Every observation we have recorded here has been a verifiable seat count rather than a display artefact, which is unusual and makes this one of the more trustworthy routes on the site.

💡 Insider Tip
Southern-hemisphere summer, December to February, is peak and prices accordingly. The shoulder months either side are both cheaper and more available. Miami has more departures than Houston.
