Manufacturer Serial Number 24517, PH-BFG first flew on 23rd March 1990 and was delivered to her KLM Amsterdam base on 11th April. She was named “City of Guayaquil”.  Almost thirty years later, her final revenue flight, as KL692, landed at Amsterdam from Toronto on 7th December 2019.  The following day she took to the skies for the final time, using an appropriate flight number KL747, to Cotswold Airport, Kemble, UK for part out and scrapping.
