The model on how holiday makers get to their resorts has been changing- tour operators now book lots of their customers on to the likes of EasyJet. It is not unfeasible if you want to expand that you buy an airline that largely carries holidaymakers and operate it as a scheduled service carrier selling seats to holiday companies. Monarch have been doing that for years and taking TCX gives a way to expand the existing business model Not so true yet in of Germany- and I doubt TUI would go that way but TCX might.
