Used Uber out of DXB this week. Driver meets you inside of the parking garage of whatever terminal you're in.
Also used uber from BKK last night again. UberX is now only 375 THB from BKK. Uber Black is still 1000 THB.
So far have used Uber in London, Paris, Helsinki, Porto, Hong Kong, Bangkok, Singapore, Auckland, Tokyo and Dubai. Overall mixed but mostly positive experience. Definitely needed to have a working phone and data plan multiple times. Will continue using Uber if the price is right.
