excellent point. at tmobile (circa 2014) it required 87 APIs be hit to turn on a new subscriber. if the 34th API failed, the subscriber had to wait and start over clogging up the stores. at the core only 3 or 4 of those APIs were crucial to start the service and the rest could have been fine with eventual consistency. who is ticketed for what flight is the core, the rest dealing with plane can be handled manually just like the small airplanes do it, manual weight & balance, flight planning, etc. but Alaska chooses not to do that and is ok losing millions of dollars per day disrupted while losing customers because they do not care. and not hiring a safety officer for years proves they do not care.
