I got this mail from Brussels Airlines (I think)
Dear UltraRant,
It's your birthday tomorrow and the entire Brussels Airlines team would like to wish you all the best for this very special occasion.
To help you celebrate, we're offering you 10% off* your next flight with Brussels Airlines.
Fly to and from any European destination in the network… From Budapest to Barcelona, Manchester to Moscow, Porto to Prague, Madrid to Milan,… It's your birthday, and you can fly where you want to!
Simply click the button below and use the promo code when booking your next flight.
As I don't have my birthday tomorrow, as I haven't booked a flight directly with SN in the last couple of years (some legs via LH, though), as I haven't provided my birthday to SN, ever and as I am not even part of their mailing list, I'm actually seriously doubting if this is an error or a phishing mail. Are there more people who received this 'offer'?
