I have to say that having used EZY several times recently, I applaud the clear policy and their adherence to their own rule, which on my booking notice was 40 minutes. On all ocassions (8) that I have flown with them in the last 3 months push back has been on time and arrival on time/early.
By way of contrast BA seems to completely ignore its own rules (gate closes 10 min before), and I can barely remember a flight of theirs that departed on time from either LHR or LGW. I wish BA would stick to their rules, not only on doors closing but also on cabin hand luggage limitations.
