Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Let me give you an example: The green carriage is of course first class. This would be our first preference with our 5 month old baby in lap, because of the presumably larger toilets for changing and whatnot. However, the baby being a Western white baby... will occasionally babble, screech or cry uncontrollably for a little while.

Speaking in terms of Japanese culture, should we avoid Green class tickets if we are taking aboard a potentially disruptive baby?

The answer to this example can be: Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car?
Here is why: A person gives a detailed description about a situation where they would prefer to travel on the Shinkansen Green Car but is doubtful if doing that would be against the Japanese train etiquette since they will be traveling with a baby. The question is summarized as Japanese train etiquette: Is it acceptable to take a baby in the Shinkansen Green Car? for easy indexing the next time someone searches for a similar phrase

OK. solve this:
I happened to be looking at a flight from yesterday (as writing) which was drastically delayed...

https://flightaware.com/live/flight/UAL48 (choose "Sept 2")

Now, on the many excellent flight info sites, you can quickly determine if a flight is delayed.

But - is there a way to find out WHY that flight was delayed?

This becomes quite critical if you're on the same flight the next day!

(Indeed for that specific flight, I notice the next day's one is unfortunately already marked as going to be delayed many hours; now I wonder about the next day.)

If you can know why a delay happened, it would surely be useful info if you're on the following versions of a flight.

Is there a way to do this?

(Often if you just "call the airline and ask", the staff in reservations often really don't know specifically.)

The sense of my question is, "If you're on one of the next flights of that flight number, to try to find what the heck is going on...!"

Answer:
Find what caused a current big flight delay?
