When your flight is grounded or delayed you need to act fast to get a seat on the next available flight. Get in line with other passengers...but boost your chances of grabbing a seat on the next flight by also calling the airline's 800 number. You may have better access to that airline's agents and therefore a set. You could program your airline's 800 number into your cell phone so you don't waste time looking it up. Don't know the 800 number? Go to http://tollfreeairline.com to find those numbers.
