This is going to be very domicile and equipment specific.

For example I went through the ORD 737 bid packet it it's pretty similar to the UA trips. Now compare that to a place like CLT which has a ton of ex-regional type flying and the trips are built very different.

Ex, in ORD I noticed a junior lineholder got a 23+ hour 4-day that was a 1-2-2-1.
