Ik kreeg vandaag deze uitnodiging van AF/KLM: ... Dear Mr. DownUnderFlyer, What if you as valued Flying Blue Elite member could help improve the quality of service by AIR FRANCE and KLM? In association with TNS, an independent research consultancy, they have designed "Quality Observer", an innovative program for observing and, where needed, improving the AIR FRANCE and KLM service on a worldwide level. We hereby invite you to join this program. If you accept and complete registration before 31 May 2015 you can be a Quality Observer for your flight KLXXXX from Istanbul, Ataturk (IST) to Amsterdam, Schiphol Airport (AMS) on 4 June 2015. ... Dit lijkt me een goedkope mannier om mystery shoppers in te schakelen. Ik krijg er wel wat voor: Each time you participate you will be awarded a 20% discount on a selection of articles in the online AIR FRANCE or KLM shop or 500 Flying Blue Award Miles. Iemand ervaring mee?
