If you do take take a look at the Aer Lingus schedule at Dublin a lot of flights have layovers of around 1 to 3 hrs between 2 pm and 5 pm allowing sufficient use of airbridges without disrupting the schedule. The main issue of not using the current airbridge is the failure of the CAA to promptly authorize ground handlers in the training of staff. Another issue which Aer Lingus used to have with the airbridge was, and I would fully have to agree with it, that they could not achieve a satisfactory turnaround time of 40 mins with the airbridge, passengers would clog the aisles and it caused a bottleneck at the bulkhead. This proved to be a particular problem with the A321 which was based to operate Heathrow flights at the time. The Aer Lingus fleet at Cork is maximized and rarely do aircraft have layovers of longer then 45 mins which means the aircraft need prompt and timely turnarounds at Cork using two stairs. The only aircraft using the airbridge at the moment seem to have long layovers (Inbound Brussels) or aircraft which are finishing there days schedule.
