I had flown Emirates several times to Dubai on business, but never able to book a chauffeur drive. There is no direct flight from my point of origin to Dubai, so I have to fly in another airline to Frankfurt for an Emirates connection. Most of the times, the tickets were not endorsed by Emirates (according to Emirates), so no chauffeur drive.

I would avoid Emirates, but it is the only airline flying to Europe from Dubai departing on regular hours and not in the early hours in the morning, such as Lufthansa.
