both JUTA and Clive's tell the traveler up front that they must call the day before departure, to confirm the return trip to the airport. if they get no confirmation call they will not come pick you up - not sure if this may have something to do with why ppl think they have been 'forgotten'.

i've used them both with great results, always an enjoyable ride with either company, and no problems. Next time i'll probably use JUTA again since clive's price has gone up and since I travel solo, either one of them works great for me.
