City Proximity (Hubs)
Sometimes you will not be able to make it back to your actual destination city (i.e. due to no availability on those flights). In this case, it is important to think about the closest cities to your final destination. If need be, the airlines could reroute you to these destinations in times of weather delays and cancellations.
These destinations are from the city centers and are measured in air miles.
