As every business traveller knows, airports can be frustrating places. A delayed flight can mean a wait of several hours. Technical problems with aircraft and a lack of available ground staff, as British Airways found to its cost last month, can cause infuriating time-consuming delays.
New security measures, brought in after the terror attacks of September 11 2001, have also prolonged waiting times, although most travellers accept that better procedures to prevent terrorism are necessary.
