All incoming newbs, listen to what this dude's said very carefully. The Airbus might be nicer, but there is very little movement systemwide as it remains the senior aircraft. That translates into years of reserve, which under the new RAS system, won't be fun for junior seniority. Most of my peers from when I started in 2023 have only moved a few percent on the bus whereas I've moved a lot more on the 737. The frustrating thing seems to be FOs spending a few years on the 737, then bid over to the Airbus once they have enough seniority to hold a line, which keep holding those at the bottom down there seemingly indefinitely.

Of course, that also depends on the base, but here in the motherland, 737 moves about 3-4x faster progression than the Airbus. I wanted the Airbus when I started, but I'm glad I couldn't hold it in retrospect.
