Global aviation data firm Cirium found that between March and December 2020, 155 aircraft globally, had all or most of their passenger seats removed in order to transport more cargo in their cabins.
Law firm Reed Smith, in a 2022 report based on IBA data, spells out the huge financial benefits that come with a narrowbody aircraft conversion, verses a widebody transformation. A narrowbody conversion approximately costs $4.2 million for a 737-800 and $6.1 million for an A321-200, respectively. Whereas, a widebody conversion of a 767-300ER could cost in the region of $14.7 million, and $18.4 million for an A330-300, respectively.
