There were two people in my class older than 53. They have hired a few FO regional pilots with no Turbine PIC.
I just finished a 3 day trip. I had a one day trip. I have had 4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19 day trips, and 28 and 31. You can work two 17 day trips back-to-back. You don't need any heavy rest if you don't go to home or base.
I am NYC based, and almost all of my trips do not start or end in base. MIA, IAH and ANC, for example, have many more trips that start and/or end in base. My buddy said it is 2+ years to hold NYC as a base. He started in ANC, then got HSV and most recently CVG (a -400 guy). MIA and IAH have a number of out-and-back trips.
Here are some NYC examples: Start CVG, end MIA. Start DOV, end Kuwait. Start BWI, end Cuidad del Estes, Paraguay. Start LAX end CVG. Start ANC, end ORD. Start CHS, end CHS. Start CVG, end LAX. Start IAH, end IAH. Start MIA, end MIA. Start ORD, end MEL. Start LAX, end LAX.
31 day month, get 14 days off. 30 day month, get 13 days off. You can be extended involuntarily about 3 days to the end of a trip (once a month max). I have been extended twice in about 3 yrs. My first 6 months online at Atlas I average 16 days/month at home. You can do R1, which is Reserve at Home.
Since I airline to trips, I normally leave home on my last day off. Two or three times in 3 years I have had to airline out on my 2nd to last day off. Normally, I get home either one day early, or two days early. Getting home two days early for me has happened a number of times.
I applied in 2007, and got hired in 2010.
Normally, you get one or two nights in a location. Min time is 12 hours, which has happened to me a number of times. Sometimes you can get 4 or 5 nights in a row off in a location. I once got 4 nights in HNL, followed by one leg, then 4 nights off in SYD (Coogee Beach). That is NOT typical!
If you have more specific questions feel free to PM me.
God bless, and good luck...
PS-I am glad I got to see my kids today. I applied at National Air Cargo in 2010, and thought they were going to hire me. When I first heard about the crash in Bagram, the first thing i thought was that it easily could have been me....RIP to the crew, and God Bless the families and everyone else affected....
