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 are at the gate fewer than 15 minutes before departure, they may already be processing standby or oversold passengers. The downside is that if there is a problem with your flight, they have to remember to cancel your check in when reissuing your ticket, especially if you change airlines.
