Depending on the day of the week and how busy they are, they may have as many as 2 or 3 shuttles running at a time. On busy days the shuttles generally work in rotation so that there is one at the airport and one at the office pick up point. these usually run at 5 to 15 minute intervals. On lighter days there may be only one shuttle and that interval time ranges from 10 to 20 minutes. I hope this helps!!!
I used the service last week and it seems the van ran every 15-20 minutes
