Narrative:
During our preflight; in a rush to try to maintain some sort of schedule integrity; since our aircraft was operating well behind schedule due to WX affecting arrs into ZZZ; we forgot to put on the fixed oxygen mask and actually try to breathe using the mask. Later discovered the oxygen was not hooked up. The pressure-quantity was fine; but the tank was not connected. We flew the aircraft from ZZZ-ZZZ1. Contributing factors to this were: 1) haste; rushing to try and make the schedule. 2) fatigue -- due to extremely early morning schedule after finishing late the previous 2 days; 3) family -- trying to commute home since our base was closed earlier in the yr; so we have some sort of family life. 4) other -- just trying to get the trip we were on over. 5) get homeitis.
