No you will not have a generous 401k match or profit sharing like you do at WN.
The last few rounds of dispatch classes at WN have been just about half or slightly over half internals. You may be better off just staying put if you are in good standing with the company, making ok money (especially if a regional would cause you to take a pay cut), and so that you can keep your vacation, continue with the good 401k match, and profit sharing. It isn’t a for sure thing to dispatch there but, if you do get on, being internal has its perks like higher seniority than the externals, longevity pay, if you have been there more than the 5 year mark or are close to it you will have more vacation days.. just things to think about. Have you tried doing a day in the field? Networking? Truly reflect on how diligent you were at studying for the test AND the interview if you got that far.... excluding something major like not a good standing with the company in your current role, something on your record, or you flat out just don’t get it, it would not be out of the realm of possibilities to eventually get into dispatch with enough networking and persistence. They are saying they could potentially hire another 60-ish after this class that is about to start next month so you could have a few more shots at it coming up. Good luck to you.
