Will my flight be impacted?

Airlines have a tendency to have a “wait and see” approach to weather, so they may delay your flight gambling that the weather will improve long enough for your flight to safely land. In these situations expect to see your departure time shifting further into the future in roughly 30 minute increments. Other flights may be canceled outright, opting to re-book passengers on flights that are more likely to depart on time than to keep the crew and ground staff waiting around when they could be better used elsewhere.

In these situations it is highly likely that your flight will be delayed, and somewhat likely that your flight may be canceled.
