AFAIK all Part 121 Passenger operations in the US (and most worldwide) have a no-fault go-around policy. Most have eliminated even the minimal requirement to denote a log entry as to the reason lest that make pilots reluctant to do the right thing. Some airlines even have monitoring programs and will penalize pilots for not going around when they should even if they save the landing. They don't want a bad habit to develop (normalization of deviance) because some day the holes in the swiss cheese will line up and the pilot won't be able to save the landing - and by then it will be too late. Part 121 Cargo and Part 135 Charter are ... another story. Quality of training and procedures vary a lot. Some are run about as well as the Part 121 Passenger operations. At others a go-around is a career-limiting move. I do not know how 21Air operated - leave that to the NTSB to discover - but it would not surprise me whatsoever if Amazon leans heavily on their contracted ACMIs and yanks contracts for delays. A go-around means an extra 15 minutes (give or take) and Amazon cuts their logistics schedules razor thin so they don't have to pay for extra labor. A 15-20 minute delay in unloading the airplane can mean the sorting center staff and delivery trucks sit idle (though it wouldn't surprise me if they just stiff the delivery contractors for the wasted time). This isn't necessarily done with ill intent - the middle managers at Amazon are just chasing their numbers and an operator that prioritizes safety will inevitably have worse on-time performance. As is often the case these days outsourcing / contracting can end up being a race to the bottom even if no one intends it that way. FedEx Ground is all contractors who bid on routes. If you ever wonder why the driver throws your package or leaves it in your driveway: they had to be the lowest bidder to get the contract and that means X deliveries per hour or they lose money. It just so happens that with air cargo operations this kind of pressure can easily lead to an accident.
