AJI, nice folks. You have to live within thirty minutes of Hobby. There is a one hour callout time. And by callout, I mean gear in well NLT 60 minutes after your pager goes off.
If you want to work at AJI, there are several qualities you should possess. If customer service is not your forte', don't bother. A pilot at AJI is also a flight attendant, aircraft cleaner, concierge, baggage handler and dispatcher. If you're not willing to proudly roll up your sleeves and take a lot of pride in being able to accomplish all of those tasks, then AJI may not be for you. There is no average trip. You'll have eight days where you'll only get called out once, and other eight day periods where your pager is going off right at 10 hours of rest. Not too many overnights, quite a few all night long air ambulance or organ flights. Again, they're going to put you to work, and when the pager goes off, you're going flying.
I won't comment on their pay system, as I no longer work there. Ask during the interview, you'll get straight answers. AJI pays its crews well. If you're a hard worker and show up with a consistently good attitude, they'll go to bat for you no matter what. I've seen several medically grounded pilots who continued to work in support positions until they left of their own volition or got their medical back.
You will grow and develop as a pilot. I've got 19 countries in my logbook, and have done flights that are simply amazing from a standpoint of getting to demonstrate a lot of airmanship. The crew force are a good bunch of folks, easily the very best part of working there. You'll get to really know the people you fly with.
Go into it with your eyes open. That pager will dictate your life. After almost six years of its shrill beeping, I needed a change and control over my life. But I'd do it all over again in a second. I wouldn't trade my experiences there (Good or bad) for anything. Great job.
