The trips however change month to month and there are big seasonal shifts. The trips with a DH at the end if it’s on day 7 are often sought after by commuters. You get a extra day of pay and positive space home. If the DH is on day 6 which happens you lose a bit of pay. Some trips are a 7 day because one of the layovers is 48 hours. In the winter you might even see 72 hours and a 8 day. Depending on the whims of network you sometimes get really strange trips in and out of other hubs.
dh SEA to JFK, JFK-ATH-JFK dh SEA as a example.
These long trips are often broken up with even more DH’s to cover with reserves or double pay GS’s. Our reserve system is very good and it makes covering long trips difficult for crew scheduling. That is why international reserve is such a good deal. One 6 day trip becomes two 4 or 5 day trips. I would often drop a trip or two off my line to cherry-pick those trips.
