Another perspective from the dark world of cargo (777 aircraft):
My March trip leaves 19 Mar for 13 days including my commute home. So, I leave on a Tuesday morning and I'll be back home Sunday midday just shy of two weeks later. I get it - not everyone would want that. There are plenty of shorter trips available if someone wanted say, two 6-day trips with a week off in between or even more trips (four 3-day trips). I prefer to minimize my commutes. As a result, I'm off 15 days in a row before the trip from 3 Mar-18 Mar. If I had worked the first two weeks of Feb, I could have had 4 weeks off in a row without using vacation. I'm working as an FO (as opposed to bidding a Relief FO trip), so I will fly a mix of long and short flights. I usually try to bid for an international deadhead to start the trip (and maybe one at the end of the trip if I get lucky) and one revenue flight each day I fly during the trip. If I wanted all long-haul flights on the trip, I would need to bid an RFO trip. Those trips typically have a deadhead (always on pax carriers, never our own aircraft) every other leg. The RFO works as part of a 3 or 4 pilot crew, has a layover and then deadheads to another city to meet up with another crew in need of additional pilots and so on.
An added bonus of bidding the FO trips (if you know who the LCAs are i.e. Instructors) is you can also get bumped if they need that trip for training new pilots. You purposely bid a trip with them knowing they're going to get a student. So, your two-week trip gets "bought" and you get paid to stay home for the month. If you still want to work that month, you can pick up an extra trip or trips (maybe over the same days you planned to work originally) and double dip (even more, if your extra trip is being paid as draft - 150%).
Day One I deadhead on AA in business class to Paris - I leave from my home airport to fly to France without having to commute to my domicile to start the trip and have some extra money left over for a private car to take me to the airport.
Arrive Paris, 24 hours off
4-pilot crew Paris to Guangzhou, China (12:01 block hours)- 29 hours off
2-pilot to Osaka, Japan (3:17 block) - 50 hours off
2-pilot to Seoul, Korea (1:51 block) 33 hours off
2-pilot to Guangzhou (4:03 block) 27 hours off
4-pilot to Cologne, Germany (12:54 block) 62 hours off
3-pilot to Memphis (10:15 block)
I get in to MEM around 0500, so I'll grab a nap in one of our hub sleep rooms (private, single bed, private showers available) and then use more extra travel money to fly home on AA with a real ticket (they'll upgrade me to first class) and another private car to take me home. Should walk through the door at home around 1400.
We do our rest periods on the 3-pilot crew the same as TreeA10. 3 equal periods. With the 4-pilot crews, we do 4 breaks (two each) as he said, but the two breaks may not always be equal. Some guys like one short break and one longer (short, long, long, short). So, a typical 13-hour flight would start with the two RFOs taking a 2 hour break while the flying crew works. Then the flying crews rests for 4-hours, RFOs rest for 4-hours and the flying crew gets another short 2-hours right before top of descent. Longer flights closer to 14-15 hours usually just mean the shorter breaks get longer. Not too many pilots I work with have much luck sleeping longer than 4-hours at one time during the flights.
That trip pays 86:21 in credit hours. Actual blocked flight hours 44:21. So, it works out to just over 6.6 pay hours per day on the trip, which at my pay rate is $1513 per day. Really efficient RFO trips can average up 8-9 pay hours per day and as a result tend to go very senior.
One other thing - We're allowed to check in to our hotel up to two days early with a deadhead on the front of a trip if we wanted. So, I could take my wife, get her a business class ticket with my frequent flyer miles on my Paris deadhead flight. Leave two days early and we get to Paris two days before my scheduled layover starts (so, really 3-days before I have to work). The day I go to work from Paris, she starts making her way home on another FF mile ticket. Since I have extra travel money (cheaper ticket from my home airport than the one FedEx planned to buy from Memphis), I can also expense the two extra days of hotel against my travel bank. End result is a 3-day mini-Paris vacation that only cost me some frequent flyer miles and the expense of ground transport to get her back to DeGaulle and to my house after her flight home.
