on domestic (inbound and outbound) its possible to achieve the 25min turnaround... sadly EZY have a habit of having such routes as "KRK-GVA" or a "FAO-ALC" and schedule them for 25mins... thats when it gets interesting, as in most cases u will have 3 man teams... by the time the steps and GPU are in thats down to 20mins (unless ofcourse theres problems with the GPU, which then means 1 guy is running around looking for a replacement, which wastes approx 5 mins) so that leaves around 10 minutes to get the bags off and then reload.. and the remaining 5 mins to get buggies, remove back steps, disconnect GPU and put tug on....
and ofcourse the possible offload of bags.. cant believe they make the handling firm accountable for any delays caused in offloading bags.. its not exactly a 2 minute job looking for 1 bag among 110 in a 737
if EZY increased their turnaround times to 30 minutes they'd run with far less delays... sure it might mean that the a/c will nightstop an hour later at night, but wouldnt that be better than missing a slot for a busy airport due to ground crews struggling?
i think the UK has the fastest easyJet turnaround time (25min) while most places in Europe/international will get 35mins+
