The problem with taking an overnight from United at ORD is that you never know whether they will actually hold their end of the deal and get you on the next flight.
It's already been reported that they could not get the passengers on next flight or the one after. In fact, the passengers would have to wait a full 24 hours for a "confirmed" seat.
Not that anyone really cares as it doesn't support the comments about one another or the airline in this thread, but like an aircraft accident there are a bunch of contributing factors which in normal times wouldn't cause a problem. This one had a detonator so it blew up.
The only surprise is that it hasn't happened before now.
Factors include:
1) Airlines, in general, being one of the most disliked industries out there, down there with or below cable companies. People already assume that the airlines won't treat them well.
2) The fact that consumers essentially have no control over the situation. The airline rules and contracts are very one sided and give the airlines virtually all the power. For most consumer transactions you don't pay until the service is rendered - with airlines, the payment is most often non-refundable and made well in advance. That further reduces consumer power and makes it very expensive (prohibitively so in some cases) to fly another airline when things like this happen at the last minute. Rebooking on another airline has virtually been eliminated.
3) In general, America is much more antagonistic these days and very divided. In normal circumstances people feel that they're being taken advantage of.
4) The airline flying experience is terrible, especially on the regional carriers.
5) Customer service folks are overworked and not well respected, so they're surly with passengers. That puts everything on edge from the get-go.
6) The air carriers overbook and have high load factors, meaning that taking a bump may mean a day or more before getting to your destintation. There is no good recovery plan. Heck, it took Delta what 3-4 days to clear up the situation in Atlanta?
7) You have very little regulatory support for the customer - the regulatory process is used to the advantage of the businesses being regulated (not just the airlines, happens with other industries, too).
8) Rules that are rarely read, and even if you try to read them they are confusing. Just look at what folks are interpreting the UA rules to be in this thread... The rules are not well explained to the customer.
9) Airlines tend to be authoritarian to enforce the rules.
And into this volatile environment, you throw a match:
9) A passenger that has his own pressures and believes he *must* be there that night. And he said "no".
Others have suggested that the regs need revision, but the fact is that would take years and not likely improve things for consumers (well, unless Elizabeth Warren were writing them). Social media will bring about change faster than regs ever can.
