Last JFK-SEA flight of the day (AA267) has been brutal lately. Had taken it several times lately and had delays so had arranged to take my family home on ISP-PHL-SEA routing yesterday, which was thwarted when inbound aircraft for ISP-PHL was super delayed. Called EXP line and asked to be moved to JFK-SEA to avoid misconnect and all 5 of us were moved (3 right into F no less). Got the other 2 up into F at check in. Invound delay + minor mechanicals meant we didnt push until nearly 10pm. Then long taxi and wait on the runway. A look at the recent performance shows a 1am or later arrival in SEA not uncommon. Ouch.
