I quoted my last summary for comparison purposes. I was hired in March 2018.
Here's how 2021 went. I'm a line holder. The alternative would be reserve, which at AA means 18 days per month (in blocks of 3-7) where you are either on a 2-hourish callout (76 hours pay/month) or 12-hour callout (73 hours/month). I get a schedule every month from the bidding software. I then use the trading tools to drop my entire schedule, with some rare trips being "sold" to others (I pay them to take my trip). I then wait for what we call makeup flying, trips leaving today or tomorrow that he company needs to fill dues to sickness, weather events, fatigue calls, delays, etc.
I fly these trips because they usually have a high pay-to-flight-hours ratio, due to contract intricacies that aren't germane to the conversation. My entire goal is to maximize my efficiency. As an example, at AA these trips pay the same
DFW-OKC-DFW vs DFW-ORD-DFW - Both pay 5:15 hours
DFW-OKC, overnight, OKC-DFW vs DFW-OKC-DFW-JFK, overnight, JFK-DFW - Both pay 10:30 hours
Anyways, in 2021 I flew 295 hours in the cockpit. I spent another 150 or so riding in the cabin as a passenger (fully paid at the major airlines). Lets call it 450 hours of actual uniformed work.
I was paid 1310 hours (this includes vacation and training pay, which are done as work-hours) plus per diem, which worked out to $241k Gross earnings, plus $30.4k of company contributions to my 401k.
So $270k in my fourth year. Recently the junior captain bid went to someone below me on the seniority list, but I will stay where I am and accrue seniority-in-seat which will allow me to further enhance my pay-to-hours-flown ration by picking up even shorter trips that pay the same as longer trip, as in the examples above.
Please note though, I am an extreme case. You have to really work the contract and scheduling tools to do what I do, but anyone can if they can tolerate the uncertainty. I spend more days home than most, so when I say uncertainty I mean you don't know what you're doing until the day before at the earliest.
As a side note, $270k seems like a ridiculous amount of money to me, but I fly with people who make quite a bit more than me, yet still live paycheck to paycheck. Please get yourself financially savvy before you start making eye-watering money. My neighbor, a wide-body captain married to a specialty doctor (total of ~$750k/year), spent years wasting everything. They tell me that Dave Ramsey saved them, and I'm a fan of his work, though I've never needed it.
