If you faced evacuation on a flight, who would you entrust to get you out safely. BA CC or Low Cost Airline.
Having worked in both charter/loco airlines and BA, I would trust the charter/loco CC in an emergency ahead of the BA CC. The SEP standards are simply not as high at BA - the way the crew cluck and get themselves upset over a couple of days a year at Cranebank is astounding. I did a crew exercise involving a Red Bomb threat in flight a few years ago, and when on the ground the SEP instructor actually advocated keeping the pax onboard so as to remain in control of them to help the police out. That was until one of the pilots suggested as there may be a bomb onboard this was outstandingly stupid.
At BA there can be an attitude of we are the best, or BA does it best with no comparison or evidence.
