The 25% discount is curious. What does that mean? 25% off the base fare? Off of a full fare class? A closer look says you have to pick one "preferred" airline.

The website misspells Bonvoy ("Bovoy") and offers "Hilton Honours Diamond Status" and "World Hyatt Globalist Tier". The early checkin/late checkout options listed include both broader brands (Hilton) and sub-brands (DoubleTree), which is sketchy.

The "business class boarding" and 2x business class upgrade list Easyjet and Ryanair as options.

The "Emerald Card", which is available for €689, offers "Marriot Ambassador Elite", "Hilton Honours Diamond", and "World Hyatt Lifetime Globalist Tier". The site also says "​Your hotel rewards status is only active during your membership period with us," so I'd be very intrigued to see how they offer Hyatt lifetime status for a temporary amount of time.

The terms and conditions seem to alternate between FoundersCard and ElitePlus. Which leads me to believe that they just cut and pasted the FoundersCard terms and did a global find and replace.

Everything about this suggests it's a scam.
