I received upgrade emails for all the sectors of my AMS-MAA-AMS trip, both for me & my wife. AMS-DXB/ DXB-AMS for Eur 385, DXB-MAA/MAA-DXB for AED 670. I bought the cheapest of Y fare, took the offer in all segments. Me- Silver, wife-blue. We got upgraded to F at the gate for our DXB-AMS segment. It was my first F travel, it was blizz :-:.

When worked out I paid exactly half the price of a normal J fare ^, F was a bonus, trip couldn't get better .
