Hi Guys,

I received a mail regarding on this

"Dear Passenger,
Thank you for choosing Malaysia Airlines.
We look forward to welcoming you on board soon.

The following are your flight details:

We are pleased to inform you that your current flight itinerary is eligible for an upgrade to a premium class cabin.

Not every flight qualifies for this new option, but YOUR UPCOMING FLIGHT IS!

Is this legit?
