It'll allow to either operate the Air Berlin routes or operate UK routes with a lower cost base and will allow them to possibly downsize UK bases or free up UK based planes to operate new routes from their respective bases or increase frequencies on current routes. It will give them quite a lot of flexibility. Another option could be to operate W patterns from PMI with the lower cost base. You could for example operate PMI-LGW-CDG-LGW-PMI or PMI-NCE-CDG-NCE-PMI. Smaller 3/4 aircraft based are quote common now with U2. Even FR operated BOH seasonally with just a couple of planes.
