I don’t know how good pax are but I think the 748I would do good here, when the A346 comes in.
Sorry we dont have a 747-800
We do have a 747-8F and a 747-8I.
As far as DIA it would be up to pax airlines or cargo airlines. I notice more and more of our Cargo airlines bringing
them into various USA Airports. I think the -8F has been to DIA at least once.
Yes,only once it was a Cargolux 747-800F doing touch n goes.
Please its the 747-8F We do not have a 747-800
