Do any airlines pay for pilot training?

Some flight schools partner with airlines to offer tuition reimbursement programs. For example, ATP Flight School has a partnership with different airlines that will make financial contributions to tuition costs for students who, following training completion, work as a certified flight instructor for ATP before moving on to a First Officer position with the airline itself. ATP Flight School offers such partnerships with Envoy and United Airlines. The Envoy program allows students to work for the airline while still instructing for ATP, providing $18,000 total in financial assistance plus benefits, with fast-tracking to employment with American Airlines. United's Aviate program is similar in structure, and offers reimbursement while providing a direct route to flying for United Airlines. Another program like this is offered by AeroGuard Flight Training Center in partnership with SkyWest Airlines. The Pilot Pathway Reimbursement program gives back $17,500 in tuition reimbursement funds for those who complete two phases of training with AeroGuard and continue on to work for SkyWest, while the Rotor Transition Reimbursement program gives back up to $27,500 in tuition reimbursement funds and bonuses for those looking to transition from rotor flight to airline piloting with SkyWest. These programs do not pay tuition while training is still in progress, because flying with these airlines requires sufficient training, but will reimburse funds upon completion.
