The flight was with easyjet
Clearly shows on boarding pass that gate closes at 0530 hrs for 0610 departure so actually 40 minutes before depaerture
Ryanair shows gate closes 30 minutes before departure
As we know airlines often close the gate after the time they say, however I've seen it numerous times, that once the last person in the queue has gone pass boarding and they are after the gate closes time they will close the gate immediatley, without announcements, especially ryanair
