Hi 
Just wondering if my flight times change, will the airline notify my travel agent?
I was searching my flight number for my upcoming trip and I found the flight for the way down, but the flight number for the way back didn't come up!! Does that mean that the flight is just full? Or cancelled? Not sure if I should wait to call the TA till a few days before or call now so I don't stress about it!
Thanks!
