you can't expect a LCC with a 30 minute turnround to get the same TLC as one that takes 90 minutes on the ground
Short haul airliners whether on the ground for 30 mins or 90 mins receive no TLC during a turnround other than a walk round conducted by the flight crew or sometimes an engineer. In EASA land there is a brief engineering check every couple of days but between that the aircraft could fly 10-15 sectors without ever being looked at by an engineer.
