The aircraft was completed in the summer of 2015, with first flight scheduled for 7 September. Windy conditions that day prevented the flight, which finally occurred on 23 September.<ref>[http://www.opb.org/news/article/experimental-glider-flies-for-first-time-in-redmond/ "Experimental Glider Flies for the First Time in Redmond"]</ref> Flight testing started in [[Minden, NV]] in fall and winter of 2015, using a new hangar donated by Tito.<ref>{{cite web | url=http://www.flyingmag.com/perlan-2-glider-preps-for-flight-tests | title=Perlan 2 Glider Preps for Flight Tests | date=17 December 2015 }}</ref> The first attempts to reach 90,000 feet will be launched from [[El Calafate]], [[Argentina]], deep in the south of [[Patagonia]], in the [[Southern Hemisphere]] soon afterwards in summer of 2016.<!--use month, as summer is January in South-->

Jim Payne (USA) and Morgan Sandercock (Australia) set a new altitude record of 15,902 metres (52,172 feet) from [[Comandante Armando Tola International Airport]] in El Calafate, Argentina. The flight took place on 3 September 2017.<ref name="2017 record"/><ref>{{cite web | url=https://fai.org/record/teamcrew-18248 | title=Glider absolute altitude record 15,902m| date=16 October 2017}}</ref>

The 2018 season was again based at El Calafate.  The project acquired a [[Grob G 520|Grob G 520 Egrett]] turboprop aircraft for use as a tow plane.  This enabled Perlan II to be towed to {{cvt|44,000|ft|0}} <ref>{{cite web|url=http://www.perlanproject.org/blog/stratospheric-tow-perlan-2-egrett|title=Stratospheric tow of Perlan 2 by Egrett}}</ref> This seems to be the highest glider tow, although such records are not registered.

The Perlan 2 could fly to {{cvt|90,000|feet}} if conditions allow, higher than the manned level flight altitude record of the [[SR-71 Blackbird]] at {{cvt|85,069|feet}}.<ref name=Airbus3sep2018>{{cite press release |url= https://www.airbus.com/newsroom/press-releases/en/2018/09/airbus-perlan-mission-ii-glider-soars-to-76-000-feet-to-break-ow.html |title= Airbus Perlan Mission II glider soars to 76,000 feet to break own altitude record, surpassing even U-2 reconnaissance plane |date= 3 September 2018 |publisher= Airbus}}</ref>
