Read elsewhere in the trade journals that LH wouldnt move to LEJ as all of the infrastructure & hub is in FRA. Interline potential currently ex-FRA would be lost and all of their current belly frt capacity on DLH pax flights would not be possible ex-LEJ!
LEJ is miles and miles away from anywhere.
Even though it is rumoured to be cheap & flexible, customers will choose the outcome. LEJ might be fine for an integrator hub, different operation from the cargo part of a pax airline!
