Upgrade times
I would expect the company to achieve about 50 percent of their goals. They always shoot high and underdeliver on hiring and upgrades. No big deal, it's just how it has been for the last 10 years or so. Just business. Temper your expectations accordingly.
As for aircraft deliveries, the investor comms rarely tell even half of the story. The company has a history of playing shell games with options, deferrals and move ups, and used airframes. I would expect a lot of chicanery this year in that regard. There are some 700s in the fleet that need to go in a big way. The COO mentioned in his town hall that we will probably be temporarily upgauging a lot of 700 flights to 800 sized airplanes in the future (due to max 7 delivery deferrals). I wouldn't be surprised to see some used 800 airframes appear as well as white tail and "other" max 8 deliveries.
I would expect to end the year at a number bigger than what the filings say, but not much bigger. What I do think will happen is that the 700 retirements will accelerate, which will set the stage for a glut of max 7 and 8 deliveries in late 2023 and beyond. The old 700s are a drag on efficiency and they have been looking to dump them in a big way since prior to Covid.
