Uber only has 21 days to lodge and appeal and whilst Uber is going to appeal against the tfl decision, a magistrate will have to decide whether Uber is fit to hold a licence in London, or not. A decision from a magistrates court could take weeks or months and unless the court decides otherwise, Uber will retain its licence during this period too. So if they appeal immediately and the case is quick, it could well all be over by Christmas (lol that famous old quote) Personally I find their service of late disappointing and the number of times my booked ride cancels (driver gets a better fare) and the app has to search again is getting worse in central London.
