We left the island on a Monday in early March. Two scanners were open and the line moved quite quickly. However, last November we flew out on a Thursday and there were two scanners open also, but the lines were very long. When we eventually got to the scanner and took out our laptops, took off shoes etc., there was a supervisor telling the operators to move faster, faster!! How can they check those screens in a appropriate and safe manner when rushed!! Not their fault there were so many travelers, the airport knows how many flights are leaving on a daily basis, it is managements job to provice enough staff to function properly. I think there are actually 3 or 4 scanners, why not use them all on busy days. In the best interest of all passengers.
