The City of San Antonio head Start and Early Head Start-CCP sites are located in the Edgewood ISD and San Antonio ISD.
A few airlines go beyond this basic requirement to include a provision that if your onward connecting flight from a hub airport is canceled on an outbound trip, and you no longer want to continue the trip, the airline will return you to your original airport at no charge and refund the entire value of the ticket.
If you haven't signed up for flight status notification subscription and your flight is canceled after check-in, you should contact United to be rebooked. If you're already at the airport, an airport agent will handle the reaccommodation process, or you can use an airport kiosk.
