You. A buddy. All the green beer you want. There’s still time to book that trip to Ireland for St. Patrick’s Day. Use 30,000 Membership Rewards points for a free economy-class companion ticket from five U.S gateways (New York/JFK, Chicago, Boston, Los Angeles and Baltimore) to Shannon or Dublin, Ireland.

To make reservations, call Aer Lingus at 1-800-IRISH-AIR (474-7424). Tell the Aer Lingus agent that you are using a Membership Rewards travel certificate. Once you have a confirmed reservation, log on to http://www.membershiprewards.com to request the certificate. You will receive the certificate within 10 business days. Upon receipt, send the certificate and the redemption reservations form to Aer Lingus within 30 days of the reservation or the reservation will be canceled.

The certificate must be received for ticketing at least three days prior to departure. A $50 per ticket rush fee will apply if the certificate is received by Aer Lingus within three to 10 days of departure. All applicable fees, taxes and surcharges are your responsibility, and must be paid at the time of issuance. Such charges will be assessed at the time reservations are confirmed. Changes are permitted prior to departure only, with a fee of $150 per change. Other conditions apply — be sure to read the fine print.

Oh, and the green beer thing — real Irishmen wouldn’t be caught dead doing that.
