Preferences - Other FFP # ?
 

Hi guys --

My first post in this forum! Anyway, I was just looking at my preferences on my Skywards account online and under the section 'My Preferences' there was a category which said 'Please indicate if you are a member of any other frequent flyer programme(s) and include your membership number for each frequent flyer programme.'

I was wondering why they asked this and what they use this information for. Thanks!
