I might add if you are on AA
you can go to
They have a tropical storm update on flights and you can also list your flight number and phone or e-mail and they will keep you abreast if there are flight delays they stay pretty much up to date.
I had a 90 minute lay over at DFW
by accident (cough cough) while I was out taking several laps around DFW
on the Sky Link AA
called my cell phone to inform me that there would be a 10 minute departure delay on my connecting flight due to a Mx problem. My girlfriend also puts my flight number in when she takes and picks me up from the airport (afraid I might get lost on the way home?)
