I based my respond from my daugther's account where the 12-month expiration date is her 19th birthday in the future. Not sure how long ago you turn 19, but if it will good if you can share with us what is show up on the email report... as the very first expiration date for anyone, regardless of age, will be Dec 31, 2013. Hence, no one could have miles expire yet right now due to the 7 years rule.
