Or there is Sharjah with Gama's FBO, the new road to Business Centre/DIFC of Dubai is now open, journey time 17 minutes on that or 25 minutes on the desert road if there's been an accident. Compare that to 45 minutes from DWC to downtown or almost the same from the existing Dubai International (before you even consider the taxi time).
6 minutes from landing to on stand; ramp access for the passenger's cars. Also, for fuel stops, the record so far is a BBJ in 26 minutes from landing to take off.
Charges are less than DWC and Dubai International. We're handling over 140 flights a month now.
I know it's blatant advertising, but it's available now as a strong alternative to DWC. And it's not what Sharjah used to be like, it's now joined up and seamless with a good bunch of expats combining it all into one point of contact.
