In Daily transit, I have added to see how some of works we can visit the LIRR page. (there was MTA page also.) And additionaly, I writed about the situation that if the lost of the metrocard. Usually, It cannot be replaced. However, 14-Day and 30-Day Unlimited Ride MetroCard and the 7-Day Express Bus MetroCard provide balance protection if purchased with a credit card or debit/atm card. So, it is better to buy the card with a credit card or debit/atm card than cash.
In airline industry, I have added discount things when we order the ticket online. For instance, in jetblue website, they shows featured webfare. (http://www.jetblue.com/) Additionally, they send an e-mail for promotion fare whenever they have.
