To vote in Texas, you must be registered. Simply pick up a voter registration application, fill it out, and mail it at least 30 days before the election date. MORE ABOUT REGISTRATION >
If you hand in your ticket early, you will not get a pro-rata refund on an annual season ticket. Annual season tickets are sold at a discount (about 25%) compared to the equivalent number of weekly tickets.
You will get a full refund for the original ticket price. Keep in mind that refundable tickets often cost a lot more than nonrefundable tickets. What you get in return for the higher fare is the peace of mind that you will get your money back if you cancel your flight. Be prepared to wait up to seven days for a refund.
