I'm on a paid $550 AA ticket for the round trip to Dublin, and a separate UA award to/from Athens which zeros out my UA account after 24 years with them. Long list of reasons I'm not flying UA but won't go into them here. Departed SFO at 2:40pm on Tuesday for DFW. Flight time was 3 hours and I watched a movie on my tablet on the way down (12 O’Clock High with Gregory Peck). My lunch choice was a very good cheese tortellini. After about an hour in the Admiral's Club lounge, off to the gate in the D terminal at DFW for the 9:55pm departure. The business class cabin was half-empty earlier in the day, but apparently a British Airways flight at LAX was cancelled and some passengers were rerouted on AA via DFW. Business was sold out. My dinner choice was blackened salmon and for dessert a raspberry torte. Tablets and Bose headsets were handed out and I listened to CDs by Boston and America. About 2 hours after departure, I was asleep and probably slept 5 hours. Woke up about 90 mins before arrival at London Heathrow and had scrambled eggs over buttermilk biscuits for breakfast. Flight time was 9 hours and we landed at 1p.m. local time. Had to transfer from T3 to T5 bus bus. Enough time for a 45 min BA lounge visit for cold drinks, then a 3:30pm departure on British Airways to Dublin, landing at 4:50p m. After clearing passport control and baggage claim, I caught the express airport bus down to O’Connell Street and was at my hotel about 6:30pm. I'm at the Maldron Hotel off Parnell Square on a 56 euro rate ($63.50). On check in I was offered the option to pay in dollars or euros and was presented a quote for dollars which was about 3-4% higher than the euro bank rate. Needless to say, I never pay in dollars when traveling as I have a credit card with no foreign exchange and this is something I'm always on the alert for.
