The 737-10 still only has one FWD door I believe so it’s not going to have a quick turnaround.
Occasionally I see Virgin disembark from the front via air-bridge and the rear via ramp and then up the stairs. I know this does not suit hot or wet weather and can run fowl of ICAO standards. If I recall Air Asia at KLIA2 wanted to continue with using roll up stairs and walking pax along the tarmac but the Malaysian DCA said no to that and made them include air-bridges in the new terminal. The resaon given at the time was the ICAO "requirement" for RPT pax to be "contained" and that walking across the tarmac for jet operations is not really compliant. I shudder to think how regional airports cope.
