[5] In January 2005, ESAS Holdings purchased Pegasus Airlines and placed Ali Sabanci as the chairman.

This was the largest single commercial aircraft order ever placed by an airline in Turkey at that time and was announced on 18 December 2012 at a ceremony attended by Binali Yıldırım, the Turkish Minister of Transport.

[12] In October 2016, Pegasus Airlines announced it was offering three of its aircraft on the ACMI and leasing markets, stating severely decreasing passenger numbers.

The breach occurred after Pegasus accidentally configured one of the Amazon S3 storage buckets used for PegasusEFB, its electronic flight bag system, to be without any security, exposing its contents to the public Internet.

Pegasus is also considering installing in-flight entertainment and charging for headphones (currently, only overhead screens are available on selected 737-800s, and they only display a computer-generated map showing the flight's progress).

As of July 2024, Pegasus operates flights to 148 destinations in 53 countries across Europe, Asia and North Africa.

The data breach, which comprises 23 million files including personal information of flight crew, is thought to have originated from a misconfigured bucket on Amazon’s cloud service AWS.

[38] Pegasus Airlines continues to operate flights to Russia despite its invasion of Ukraine and the resulting international sanctions.

While most Western airlines have ceased operations in or over Russian airspace, Pegasus maintains its routes, aligning with Turkey’s close diplomatic and economic ties to Moscow.
