No dog in this hunt 'ceptin I hope Delta gets an awesome contract so UAL has a big target to hit in 2018, but having said that here is my take of the above:

6 months / 93 days = 15.5 days worked per month or 14 days off on average.

At UAL, as a 20 year FO on the 764 I get 21 days off average (including vaca and sic) and am within $10k of the above with a far inferior contract but plenty of Premium Pay and Senior Manning. Whats the value of 7 days per month at home? And, I should note, I leave my house on day 1 around 3 PM for a 6PM flight then I'm home by 4PM on the third day so really I'm gone from home 48 hours or just over so to be honest I'm really working 6 days a month. I'm a guy who wants max time off, but I just flew my last trip with a guy who had a pay claim issue so he was showing me his monthly statements and he's averaging over $20k per month and he's still averaging 15 days per month off, again because of Premium Pay and Senior Manning.

Comparing SWA to Delta or United is disingenuous. They are VERY different animals and I would argue even VERY different jobs. I never applied to SWA and never would. Thats why Baskin Robbins has 31 flavors, something for everyone to be happy.
