You could extend for 2 years and they could give you a one year remote (flying or not...whatever) to thank you for your service. Or you could be in a "flying" job but be put in charge of (name an FGO job) and still not have the 100 in 12 that is needed to go directly to most majors. Then you wasted 2 years. Go to the regional, get current in 3 months, then be at a major within a year. Don't look back.
