If a pilot with experience on type joined any airline, it’s still going to cost them lots of money to train the pilot up and get he or she online, particularly if the pilot has been off the type or out of flying for a while. What’s really the difference in a non type rated and type rated pilot with relevant experience on other similar types from a cost of training perspective? Probably next to nothing. Airlines are happy to take the profits, however they like any other business that employs technical people should be investing money into training which is at their expense, not the employees should circumstances change.
