I fly with a lot of lifers these days, most of them stayed because of QOL. While I'm sure the raises will be enough for a handful to change their minds, most that I talk to say they don't want a commute to reserve for the last few years of their career. They would also stand lose a ton of vacation time, which is another common reason I hear. Most of these guys could have made the jump 4 years ago, so it'll be hard reverse that decision now. We'll find out in a couple months.
