I have been flying EK every month for almost 10 years, they have the best Economy product in the world, however their Business class seat value is slipping
So last year I flew some flights on QR for a promotion and am now Platinum / oneworld Emerald which is quite cool as I have never participated in an alliance
I will continue to fly EK but flights originating in Dubai will likely be on QR in future
the "dine on demand" service on QR Business + offerings puts EK to shame, to many crews rush through the service and food has less good though the wines exceptional
connections are an issue and few flights will be good if the crew sucks on either
