For goodness sake, when will this thread attract professionals with an understanding of airline business rather than the waffle of individuals like Rivetjoint.
Flybe are doing nothing different to other airlines. If pax prefer KLM then Flybe will realise and reduce capacity. If pax use the Flybe service to the detriment of KLM, then either KLM need to up their game or pax simply prefer what they are familiar with.
As a comparison this is no different to Jet2 at BHX opening the same routes than Monarch and Ryanair, or Easyjet and Ryanair at LTN, or Wizz deciding LTN needs a fourth carrier on the Tel aviv route. Or, heaven forbid KLM starting a service that Flybe already offered out of Southampton.
I appreciate some people dont like Flybe regardless. But without them SOU wouldn't be as busy as it is today. Personal opinion should sit at private conversation, professional conversation ideal for the wider forum that is Pprune.
