> I have a series of screenshots and recordings where United would change information on their official app from, say, insufficient crew, to crew rest, to blaming weather.
Is very close to one of the many ways Best Buy got in trouble. Back in the day, their website would detect if you were looking at the website from a store-associated IP address, and display different pricing.
So when you shopped around at home and found your $200 hard drive, went to the store and saw that it was $300, the clerk could pull up the website and say "oh, no, you were mistaken, see?"
That started falling apart when cellular data plans became common place and people turned off Wifi and said "Well, huh, when I'm not connected to your network it shows a lower price. Please explain."
(Then there's the retailer specific SKUs... "Sorry sir, this hard drive is a WD8TB7200-BBY, not a WD8TB7200-AMZN, so it's not eligible for price matching"...)
