Obligatory “fuck United”.

They fucked up my vacation a number of years ago and I have since sworn them off. The most generous interpretation of the incident is that I missed an email updating a time change and arrived at the airport after the flight had left. Their next flight wasn’t until the next morning. My wife and I were looking and there was a flight from a different airline that would have cost them $400 each to book for us (they wouldn’t refund us so we could purchase that separately). The first agent at the counter completely understood our request but simply didn’t have the authority to make that decision. So she got a supervisor. The supervisor did that annoying ass thing where they listen to your request and then restate it in objectively different terms to sound unreasonable. In the end they covered a hotel for the night and gave us $550 each in travel vouchers and lost a customer for life. So they ended up paying way more and lost a customer than had they not fucked around from the start. Had they paid the $400 from the beginning, we’d have given them much higher preference on our future flights which have been many.
