I have a 10 am flight on Sky Airlines on Tuesday. If I arrive at EZE two hours early, should that be enough time to check bags and go through security? How much time should I allow from Palermo Soho to the airport at that time of day? Will Uber be available? Or will I need to hail a radio taxi (and will it be easy to hail radio taxi at that hour)? I shouldn't take a non-radio taxi right for safety reasons, should I? I've been using Uber since I got here which was easy.
