American airline companies landed their last passenger 747 jet into retirement last year citing higher costs of flying this aircraft in comparison to modern widebody twin-engine aircraft designed for the same purpose.
Is it possible to buy a passenger version of the Queen of the Skies (747-8) for use elsewhere if the costs of flying are not a problem and profitability in light of buying second hand compared to much expensive new aircraft? Will the FAA allow this if the aircraft is airworthy and for how long will Boeing keep maintaining its aircraft in terms of manufacturing spare parts and supporting it?
