From 01 August 2018, Emirates Skywards will become the loyalty programme for flydubai (sister company of EK), replacing OPEN, the old programme. This means everyone will be able to use an existing Emirates Skywards account to earn and redeem Skywards Miles when flying with flydubai, as well as with Emirates. Skywards Silver, Gold and Platinum members, as well as Open Gold members, can convert their Flydubai points into Skyward miles. For me personally (i am Gold member of both airlines), I was offered to change 2:1, meaning 50,000 Open points to 25,000 Skyward miles. Or the alternative of a Flydubai voucher of ca. 300 AED.

Flydubai did imho not consider the small but important tier benefits Skyward Silver, Gold and Platinum have.

1.) Lounge
Silver members can use the EK lounge in T3, same for Gold (Business Lounge) and Platinum (First Class Lounge), who can also bring another guest. This will be impossible at the Flydubai Terminal, as their Lounge is very small. Flydubai on request already confirmed that using the Lounge in T2 will not be a tier benefit (I thought so).

2.) Business Gate T2
Skywards Silver and above using the business gate for boarding. As T2 is using a bus to bring the C Class Pax to the aircraft an there are only 16 seats in that bus, I can not imagine how all Skywards member + the regular C-Class pax will fit into it.

3.) Luggage
Flydubai didn't comment yet on the additional luggage allowance for Skywards and check-in. procedure.
