True, but won’t be doing 1 and 2 day trips like what’s in the title of the thread except in a relatively small amount of companies without seniority. Takes years to get that seniority, except in bases where everyone commutes. Also, unless the OP wants to be moving to a new base for his upgrade, and then again when moving on to a major, and then again when upgrading at said major, and possibly with equipment changes at said major, then the whole 1- 2 day thing can easily fall apart.

If you stay in the same seat in the same base and ride the seniority wave then you’ll be able to hold that type of thing when you get the seniority and as long as the music doesn’t stop (bad economy, wars, etc). This would slow progression in your career, but then that comes down to what matters most to you. To progress at a “normal” or faster pace, if there is such a thing, then 1-2 day trips probably won’t be a thing in most 121. But having 12 nights gone could be a thing, especially living in base.
