Changing your flights to an earlier flight is something frequent fliers do with some regularity. This should be done with care and with all the information possible. Case in point: On a recent trip I arrived at the airport purposely early due to poor weather conditions in the area. I was delighted to see an earlier flight was delayed but still leaving an hour before my original flight. I had the front desk change my reservation – in my elation I didn’t ask any questions. I arrived in the gate area only to hear an announcement that the flight I was now booked on was leaving later due to equipment problems, not weather. Bad move on my part (I was joined by others who fell into this same trap). Fortunately, I got back on my original flight (standby) and actually got my original seat back. TIP: Always ask questions about delays, don’t assume anything.
