Congrats and love the enthusiasm... there’s been a lot made over guys with only single seat time struggling with airline ops, but it really depends on the individual. The last couple I’ve had in training were awesome! They understood that they had a lot to learn and buckled down. Also left their attitude at the door. They were very accomplished in their pre-United career, as it sounds like you are, but realized that as much as we appreciate their experience (that’s why they were hired) they are no longer ace of the base. (That goes for all new hires)... Point being that with the right attitude and work ethic, you’ll succeed at training no matter what your background is.... it’s sounds like you have the right attitude coming in and hope to see you in training soon! Congrats and welcome!
