Atsa Airlines

Atsa Airlines (4A) is a Peruvian airline based in Lima, with Jorge Chávez International Airport as its main hub. For travelers, it is best understood as a regional Peruvian carrier: Atsa’s scheduled passenger operation links Lima with domestic destinations such as Andahuaylas, Chachapoyas, Huánuco, Mazamari and Tingo María, while the broader ATSA business also includes charter, cargo, VIP, medevac and aviation-support services. I found no official indication that Atsa belongs to oneworld, Star Alliance or SkyTeam, and its own booking page labels mileage use as “coming soon,” so travelers should not assume alliance earning, redemption or reciprocal elite benefits unless Atsa publishes a current rule for the fare being booked.
