Physical copies of airline tickets are not mailed. Instead, travelers are able to access boarding passes for their flights like this:
1. Approximately 24 hours before a trip, Travelocity and/or the airline itself will send an email alerting you that check-in is now available.
2. This email will guide you through check-in on your airline's website or app.
3. After completing check-in, you can print your boarding pass at home (there will be a print button at the end of the check-in process), or use the airline's app if an electronic boarding pass is preferable.
