Gold mine? Well....how about a good iron ore open pit mine. Good solid work--you won't get rich but the extra income can be great on first year pay. You will have to work, but especially if extra days are out there, life can be good. Many guys in my unit have been able to get 139 MPAs (total for FY) to go along with the 48 UTA/AFTPPs.
Some furloughed guys have gotten orders to augment various units for 90-180-365 days or so. Problem is that while the money and benefits are nice, there is no guarantee of future "man day" availablity...so even if you are troughing hard at the moment you have to be pragmatic and save some funds for down the road.
As for lifestyle...I made a VERY tough call to pass up working for one company to work for FedEx. Turns out I really enjoy FDX, but one of the primary reasons I chose them was the easier commute, as I knew I'd be living near my ANG base. If you are close, you can have a very comfortable quality of life working locally and being home at night, then hitting the road on airline trips. If you live in domicile, you can probably get a similar lifestyle bidding reserve, but I imagine at the end of the month you will have been away from home more days (since you'll get called up some) than if you lived near your military unit. I've know a few guys who double commuted for a while, but all will tell you its a tough road.
I actually started to respond just to emphasize you shouldn't expect to "get rich" doing ANG/Reserve duties. On the other hand, an extra 20-40k per year can help get you through rough times, and being able to "drop" a trip here or there with mil leave can sure make momma and the kids happy when you are home for special events. Nothing is free, however, and there are some real costs.
First...when the schedule a war...you may have to go. If they schedule a war after you are off probation and making great money as a Captain...well...you still get to go!
Second...you have now doubled the ways to screw up and kill yourself. Only you can decide how much/little flying you need to do to stay current at BOTH jobs, with two different (sometimes radically different) airframes, different missions, etc. I had 10 years experience in my military airframe before leaving active duty, but now flying it in the ANG I still cannot "coast" but have to stay up on the latest new avionics, tactics, comm changes, etc. At the same time, your airline still expects you to sail through all your checkrides and sims. I had a line check at my airline in Oct, an AF Instrument checkride and sim in Nov, a mission check (tactical employment) in January, and am due for another airline sim check in March. None of it is overwhelming, but my point is for every sim or check you study for, you will soon get to study for twice (or more) as many. Add upgrades if you are learning a new jet (MQT, flight lead, mission commander, instructor in fighters or MQT, airdrop, aircraft commander, AAR, IP, etc in heavies) and either way you will have a full plate keeping up with everything some days.
Don't let me scare you away, however...if you can make it work it really is a great way of life. You get to be an airline pilot with the associated benefits, but when you see bad things on CNN you can look in the mirror and know you are hopefully doing something to help serve this great country along the way. You can't buy that feeling, and no kidding...having done this for a year...I've been very greatful for the money but even happier to still be part of the team.
Good luck.
