I used to use Alpha very regularly when I was doing FIFO work or traveling however after having three trips in a row where the bus took over 30 minutes to come and pick me up despite them knowing the time I was landing and ringing them to let them know I landed I refuse to use them again. One time I was waiting for almost an hour watching numerous other airport parking buses come and pick up their passengers and there was not even a hint of an apology or offer for a discount when I raised my complaint with them,.
