Good afternoon!! My name is Sergio Alvarez Garcia and I am studying at Loughborough University (UK). I would like to invite you to take part in the survey for my dissertation about the Frequent Flyer Programmes (there is no need to belong to one of them to take part in the survey). It only takes around 3 minutes and I would really appreciate it. The survey will be closed on August 5th and the results will be posted on August 19th. https://lboro.onlinesurveys.ac.uk/frequent-flyer-programmes-trends-in-customer-profiles Thank you so much!
