I was reading this article over at MSNBC http://www.msnbc.com/news/443507.asp...menu.asp&cp1=1 and a few things were news to me. Wanted to get others opinions about them.
Such as:

4. Remember rule 240. Remember that paper ticket
advice? Couple it with rule 240 and you have a halfway
decent chance of getting out of town in the event of a delay.
Rule 240 (many airlines may know it now as Rule 120.20)
had its beginnings under the old pre-deregulation Civil
Aeronautics Board, but thankfully survived the
post-deregulation transition to the U.S. Department of
Transportation. What is rule 240, you may ask? In the event
of any flight irregularity of any kind (with the exception of
weather), invoking rule 240 means the original (and
delayed) airline takes your paper ticket, endorses it over to
the next available flight, not their next available flight, and
off you go.

5. It’s not the flight number, but the aircraft
number that makes the real informational difference.
If your flight is showing up as on time, or even if it is
showing up as delayed, you need accurate information. So,
call the airline and ask them the aircraft number assigned to
your flight. Then ask them the actual status of that aircraft
number. For example, let’s say you’re flying from Seattle to
Chicago on the 2 p.m. flight and it’s now noon. You ask
and are told the plane is on time. But then you ask for the
aircraft number, and discover it is aircraft number 423. You
then ask the status of number 423 and learn that this aircraft
is currently in Topeka. Guess what? You’re not leaving at 2
p.m. The same applies for flights already listed as delayed.
If the plane is not at the gate, do the same routine to
determine how long the delay will really be. And, as a
general rule of thumb, add 20, 30, 40 or 60 minutes to the
actual arrival time of that flight to determine the earliest
departure time of that flight, depending on aircraft type
(737, 727, 757 or 747).

There seems to be some back and forth about Rule 240 and I did not know about the other at all. How about you veterans?
