Bombardier pays more initially, because they have less to offer, especially in the long term. However, I've heard that they are a good company to work for, with lots of ex-mil guys flying there. Someone could put in a full career at FedEx or UPS or any airline, then retire and still get a job at Bombardier. Much like FeDelta did with FedEx and Delta. Good work if you can get it.
