If you are planning flights with Emirates or FlyDubai until March 23, you should book them by January 24 to secure a good start to the New Year as a Skywards member.
For all these flights, you earn double miles.
After the recent changes, the Skywards program has become more interesting for reward flights in Economy Class, but significantly less so for reward flights in Business or First Class. Double miles on one or two flights will at least partially compensate for this, but certainly not entirely.
