The hundreds that will be unfrozen in the next few years wont get LH courses straight away once unfrozen. Why would the company 'pay' for airbus FO to do a LH type rating and then have to replace them with another FO on the airbus. They'll just type rate one new DEP onto LH. It's about money. There will be claims of training capacity etc etc but seems fairly simple maths to me. One type rating, or two?
