TNT do indeed lease Bluebird Cargo aircraft and have hired in Icelandair B733F also for a long term in the past for the LGG-ATH-LGG route.
TNT will continue to lease in third parties until they have a suitably large enough fleet of 73s of their own.
And whats all this about a pax operation??
Its not core cargo/courier/freight business, are you saying TNT or DHL are interested/proposed pax startup
