Please consider adding a filter function to allow one to exclude flights from a departure or arrival city. For example, I would like to see only Delta and it’s affiliate carriers departing out of Memphis, TN. Enabling me to exclude airlines such as American, USAIR, ect. would help me get to the data I seek. Or, conversely, allow one to include only certain airline identifiers in the presented data. Which ever is easier.
Thank you for your assistance.
