My old airline received a new airplane every 10 days for almost 3 years. We hired over 4000 pilots in 6 years time and never had to compromise training or even think about DECs. They would have had their legs broken anyway if DECs came on the property.
Why do some pilots think with this "huge" delivery schedule we have to hire DECs at Emirates? We have plenty of qualifed and deserving FOs already on the property.
It is not a big deal to upgrade the FOs already here and hire new FOs to take their place.
150 DECs will delay the upgrades for the FOs here by at least 1 1/2 years.
