Lessor AviaAM Leasing is acquiring another pair of Boeing 737-800s which will undergo passenger-to-freighter conversion.
The company has identified the twinjets as MSN29769 and MSN28225 – respectively 1998 and 1999 airframes.
They were formerly operated by carriers including Caribbean Airlines, Turkish Airlines, and SunExpress.
AviaAM says the aircraft will take the number it has inducted for cargo conversion to six.
It has been delivering the aircraft for operation by Icelandic carrier Bluebird Nordic.
Three have already been handed over and a fourth will be delivered in late January, the lessor states.
The latest pair are being modified at the STAECO Taikoo engineering facility at Jinan in China.
Conversion is scheduled for completion by the second quarter of next year. AviaAM Leasing chief Tadas Goberis says the programme is providing operators with “more efficient” cargo aircraft.
